This document discusses environmental impacts from offshore wind farms, including impacts during construction, operation, and decommissioning. It notes that construction can impact marine animals through noise from pile driving but that operational impacts appear minimal. Operational impacts on birds may be less than 1% collision risk, and wind farms may create artificial reefs and fish refuges. Planning and environmental directives aim to ensure cumulative impacts are considered and good environmental status of oceans is maintained.

Forests play an important role in climate change mitigation. As the global middle class expands by 2 billion people by 2030, a circular bioeconomy where biological resources replace fossil fuels could help ensure prosperity within planetary boundaries. Forests covering 43% of the EU are key to resilience as they support biodiversity, water, soil and provide a climate mitigation effect equal to 13% of emissions. Using wood in construction instead of cement and steel avoids 2 tons of CO2 emissions per ton of wood. Sustainable forest management can increase carbon sinks while reducing drought and fire risk, and forestry measures across the EU could increase mitigation potential by 35-70% by 2050.

Presentation by Prof Steffen Boehm from Essex Sustainability Institute - University of Essex on The Radical Emission Reduction Conference: 10-11 December 2013.
Connecting IPCC and COP, and the Asian energy reality
The bulk of incremental global CO2 emissions comes from Asia Pacific driven by India and Southeast Asia. In a Paris-compatible scenario, India and Southeast Asia would need substantial reductions in coal power and increases in renewable energy. However, there is a large gap between the COP/IPCC narrative and Asian energy reality. Coal remains the most abundant and cheapest resource in countries like India. Raising energy prices through carbon taxes is extremely unpopular, especially in developing countries where priorities lie with education, healthcare, and jobs over climate change. Carbon neutrality will only be possible when zero-carbon technologies can be deployed at affordable prices.
Keynote commentary by Mike Muller - CP meeting Day 1
The document discusses challenges and opportunities around food and water security in South and East Africa in the context of climate change. It notes that while constraints currently exist in agriculture and land, water can support food security if user sectors are engaged. Regional approaches and cooperation between countries and agencies are needed to develop food and water security plans that consider realistic timelines and local ownership. Private sector actors are recognizing both economic opportunities and responsibilities to local livelihoods in this area.
Hydraulic fracturing presentation
This document discusses hydraulic fracturing (fracking) and debates around its environmental and economic impacts. It covers topics like the technical process of fracking, potential issues like water contamination and air pollution, benefits for energy production and jobs, and policy options for regulating the practice. Critics argue fracking can harm the environment and public health if not properly managed, while proponents say it can provide economic gains if risks are addressed through rules and safeguards. The document examines these various perspectives on the risks and rewards of increased shale gas development through hydraulic fracturing.
Arps public lecture brook
Professor Barry W. Brook gave a public lecture on clean and inexhaustible fission energy. He discussed how carbon pricing changes the relative competitiveness of low-carbon baseload generating technologies like nuclear energy. Brook argued that replacing fossil fuels by 2050 will require a partnership between Generation III and Generation IV nuclear reactors, as Generation III alone could escalate fuel and waste costs while Generation IV ramps up too slowly on its own. Brook provided examples of Generation IV reactors already operating or coming online in India and China to support the feasibility of this approach.

Viterbo Offshore Wind Energy In Brazil
This document discusses the potential for offshore wind energy development in Brazil. It notes that Brazil has the third largest offshore wind resource in the world. While Brazil has made progress in developing onshore wind power, there is still opportunity to strengthen research and development of offshore wind energy projects, both nearshore and further offshore where oil extraction already occurs. Offshore wind energy could help meet electricity demand in coastal load centers and diversify Brazil's energy portfolio. The document argues Brazil should pursue offshore wind energy to gain strategic advantages in energy supply, industrial development, and participation in clean energy markets.
Green (cell) shipping
The document discusses Green (Cell) Shipping as a method to increase sustainability and efficiency in the shipping industry. Green (Cell) Shipping involves powering ships primarily through renewable energy sources like solar and wind power stored in on-board batteries. This allows ships to reduce or eliminate their reliance on diesel engines and fuel. The document provides several examples of pilot projects using this technology, including a converted research vessel in Canada and cargo ships in Europe powered by hydrogen fuel cells and solar panels. It concludes that while renewable energy technologies still need improvements, Green (Cell) Shipping has the potential to significantly reduce emissions and costs in the shipping industry.
Renewable Energy
This document discusses the problems caused by burning fossil fuels and proposes renewable energy as a solution. It defines renewable energy as solar collectors, photovoltaic panels, and wind turbines. It also references a T. Boone Pickens TV commercial promoting wind power and questions what the future holds for Earth. In conclusion, it lists several sources that provide information on investing in wind turbines, mobilizing to save civilization from climate change, government resources on energy efficiency and renewable energy, global renewable energy reports, and energy basics.

Andy Cotugno examines the relationship between land development patterns and motor vehicle travel in the U.S. and assess whether petroleum use and CO2 emissions could be reduced by changes in development design. Mr. Cotugno reveals how compact and mixed use development, and residential density directly correlate to a healthier environment, while acknowledging the challenges of economic and political reform.A World of Energy
This document provides an overview of energy, including definitions of key terms, units of measurement, historical and current patterns of energy use worldwide, projections for future energy use and the types of energy including fossil fuels, renewables, and nuclear. It discusses trends in population, GDP, and carbon dioxide emissions and considers whether the global energy system can stay below 450 parts per million of atmospheric CO2.
IPCC Special Report on Climate Change, Oceans and Cryosphere (2019)
The document summarizes key findings from the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate. It finds that:
1) Over recent decades, the ocean and cryosphere have experienced widespread changes due to global warming, including shrinking glaciers and ice sheets, reductions in snow cover and Arctic sea ice, and increasing permafrost temperatures.
2) Between 2006-2015, the Greenland and Antarctic ice sheets lost mass at average rates equivalent to 0.77mm and 0.43mm per year respectively of global sea level rise. Glaciers lost mass equivalent to 0.61mm per year.
3) Arctic sea ice extent has declined significantly for all months since 1979, with
Worlds without nuclear3
The document summarizes a literature review on achieving 100% renewable electricity. It finds the evidence for feasibility is limited, as many studies do not fully simulate electricity supply and demand or consider transmission needs. Large-scale hydro and biomass play essential roles in most simulations, but these have environmental and social impacts. The document concludes decarbonization likely requires expanding nuclear power faster globally, as exemplified by countries like Sweden and France that have low-carbon grids combining hydro, nuclear and renewable energy.

Resources waste
World population and consumption of natural resources have both increased dramatically over the last 50 years, with resource consumption rising 1000% and over 90% of extracted resources becoming waste within 3 months. Unless consumption patterns change, current rates of resource depletion are predicted to exhaust known reserves of many essential materials by the end of the century.

Will Technology Destroy The Planet?
The document discusses both the pros and cons of technology's impact on the environment. On the pro side, it outlines various renewable energy technologies like hydroelectric, wind, solar and geothermal that can help reduce environmental impact. However, on the con side it notes that climate change poses an existential threat if carbon emissions are not reduced rapidly. Certain existing and potential technologies also risk catastrophic destruction if misused, like nuclear weapons. In conclusion, the effect of technology on the planet remains uncertain, but renewable technologies need further development while curbing climate change and limiting weapons proliferation.
China s energy plan to reduce its dependence upon coal
China is seeking to reduce its dependence on coal and improve energy efficiency in order to address environmental and safety issues. It plans to slow coal mining expansion over the next five years and increase regulation of the industry. China is also pursuing natural gas, nuclear, and methane from coal as alternative energy sources to lower air pollution and greenhouse gas emissions. Developing coal bed methane is seen as a potential economic source of natural gas that can also improve mining safety.
Michigan Energy Forum - December 6, 2012
Natural gas has dropped in price drastically in the last several years thanks to new drilling technologies such as "fracking." This change in the economics of power generation is prompting manufacturers to explore gas powered co-generation and prompting utilities faced with an aging fleet of coal fired power plants to consider replacing them with gas powered electrical power plants in light of their cheaper costs. Burning less coal could reduce polution and GHG emissions, but fracking raises some concerns about ground water and safety. We will discuss the impact of fracking on natural gas prices and its impact on our fuel source mix and the economic opportunities, environmental impacts, regulations, and concerns being raised by this technology and market dynamics it is facilitating.
Wind Energy
The document discusses the environmental impacts of both inland and offshore wind farms. For inland wind farms, it outlines visual, noise, wildlife, shadow flicker, electromagnetic, and land use impacts. Visual impacts include visibility zones up to 400 times the turbine height. Noise can cause sleep disturbance. Turbines pose collision risks to birds. Shadow flicker can cause undesirable flickering. Offshore wind farms also impact animal navigation and attract seabirds, increasing collision risk. While wind energy is cleaner than fossil fuels, its large-scale deployment could significantly impact the environment if not properly managed.
201308ppt1 (King Island Workshop, 20 May 2013)
This document discusses the ecological impacts of wind farms, including impacts on birds and bats during construction and operation phases. During construction, habitat clearance and noise/visual disturbances can negatively impact some bird populations within 600 meters. Operational impacts include direct mortality of birds, especially migrating songbirds and raptors, and bats, with the highest bat mortality occurring near forested ridges. Mitigation measures aim to site wind farms away from important habitats and use techniques like curtailment, feathering, and radar to reduce avian collisions.
Acoustics and vibrations of marine renewables- Mark-Paul Buckingham
Xi Engineering Consultants will share their expertise in this field and discuss their latest research on the noise effects of operational offshore wind turbines on marine species that commonly occur in the Irish Sea.
Network Opposed to BNPP Combined Presentations
The document summarizes arguments against reopening the Bataan Nuclear Power Plant in the Philippines. It cites safety and environmental concerns given the plant's age and location in a seismically active area. It also notes there are alternative sources of electricity like geothermal, natural gas, and renewable energy that could meet the projected shortage in 2012 without operating the nuclear plant. Additionally, reopening the plant would impose significant economic costs on consumers through a nuclear tax and debt from the high costs of construction, decommissioning, and waste disposal. The global financial crisis also warrants reevaluating electricity demand projections and determining if reopening is truly necessary.

Wind power ppt
Wind power is a renewable energy source that can help address Pakistan's electricity needs. Pakistan is working with China to install 14 small wind farms in remote areas of Sindh and Balochistan that currently lack electricity access. Wind power has benefits like being clean and creating economic opportunities, but issues include maintenance needs and unpredictable winds. When operational, it could have positive environmental and economic impacts through avoided pollution and job creation.
Environmental Friendly Coal Power Plants
Carbon capture and storage (CCS) is a three-step process to reduce carbon dioxide emissions: 1) Capture CO2 from power plants or industrial processes, 2) Transport captured CO2 via pipelines or ships, 3) Inject CO2 deep underground for long-term storage. CCS has potential to reduce greenhouse gas emissions by 80-90% and enable continued use of fossil fuels for electricity generation while mitigating climate change. However, CCS also faces challenges of high costs and uncertainties around long-term storage and potential leakage of injected CO2.

An Evaluation of EIA report of Norochcholai Coal Power Plant Sri Lanka
The Lakvijaya power station or the Norochcholai power plant is the first coal fired power plant in Sri Lanka which is located in Narakkalli, Norochcholai in Puttalam district. It was proposed to establish in 1993 and was suspended the construction due to protests by the villagers and environmentalists. The environmental impact assessment (EIA) was conducted regarding the project in 1998 and the constructions began in 2006. The phase one with a capacity of 300MW was commissioned in 2010.
Ceylon Electricity Board (CEB) was the project proponent and Coast Conservation Department was the project approving agency for the project along with the central environment authority. The EIA Report (EIAR) mainly focused on the power station land, the transmission line land, marine resources and sea water quality, ground water resources and quality, cooling water effluents, solid & liquid wastes, air quality & noise and socio-economic aspects of the area.
The effects from fly ash and bottom ash, emission of SO2, NO2 & other gases, impact from discharging of warm water to the ocean, effects on livelihood of residents were the major predicted impacts of the project. Necessary mitigation measures were also suggested by the EIAR.
But, as the power plant operates, several other impacts which were not mentioned in the EIAR were also identified.
Frequent proper monitoring of emissions and impacts, conducting researches and studies on the power station and the related environment, using fly ash as a raw material for other industries and encouragement of alternative energy sources other than coal power can be proposed as recommendations.
Environmental impacts of renewable energy production"
Coal has the greatest environmental impacts of all energy sources due to its high greenhouse gas emissions, water pollution, and health impacts. Wind and solar have the lowest impacts with minimal greenhouse gas and other air pollutant emissions, though they require large amounts of land. Nuclear power also has relatively low emissions but generates radioactive waste with no long-term storage solution.
Natural gas
The document discusses the opportunities and issues around natural gas. It notes that natural gas power plants are more efficient than coal plants and produce fewer emissions.

Environmental and Social Impacts of Hydro-Electric Dams in Chamba District o...
Having 4300 large dams already constructed and many more in pipeline, India is one of world's most prolific dam-builders. Large dams in India are estimated to have submerged about 37500 km2 land area and displaced tens of millions of people. Himachal Pradesh is proceeding towards power-surplus state and there are as many as 401 projects of different magnitude in different stages of installation on 5 river basins of the state i.e. Satluj, Beas, Ravi, Chenab and Yamuna. State has identified its hydropower generation potential at 23,000 MW. The ecological devastation caused by various projects at lower altitudes of Himachal Pradesh has been alarming; while the prospect of what will happen to the fragile alpine ecosystem is frightening. These projects will change the microclimate that will result in accelerated melting of the snow and glaciers at high altitudes. Like other river basins of the state, hydro-electric power generation in Chamba district was started in 1980s, with 117 mini & micro power projects in different stages of execution at present. Having the special focus on Hul projects the present paper explores the impacts of various dams on environment and local people in Chamba district of Himachal Pradesh. About 6000 local people are being affected by Hul-I project only. The consequences to nature and wildlife will also prove disastrous. As of now, the wildlife such as deer, bear, goat, tiger and peacock do not enter the fields of farmers. Deforestation and soil erosion are even more devastating. Making the situation even more absurd is that the benefits of these power plants do not go to the community suffering the consequences. Gujjar and Gaddi tribes in the state of Himachal Pradesh have been agitating against 4.5 MW hydropower plant from diverting the entire flow of the Hul stream, on which their lives depend. These communities have for more than two decades protected and preserved the forests from which Hul stream originates. The project’s pipeline is said to destroy about 2000 of slow-growing oak trees. Livelihood and social impacts of poorly planned mini-hydel projects can be thus devastating, as exemplified in this case.

EIA thermal power plant
The document provides an environmental impact assessment of a proposed thermal power plant in India. It summarizes the typical coal-based power generation process and identifies the main environmental issues as air pollution, water pollution, noise pollution, and land degradation. It then analyzes the impacts of activities involved in setting up and operating the plant. Finally, it discusses remediation measures that can be taken to mitigate the environmental effects.
Thermal pollution
Thermal pollution is the harmful increase in water temperature that can be caused by power plants, factories, and the removal of vegetation near bodies of water. It impacts aquatic life by decreasing oxygen levels and altering ecosystems. Even a small temperature increase of 1-2 degrees Celsius can kill native species. While thermal pollution from industrial sources can be controlled through techniques like cooling towers, thermal pollution from devegetation is more difficult to regulate due to cumulative minor impacts from many actors. Laws and erosion control efforts can help address this type of thermal pollution.

Indonesia is highly vulnerable to climate change risks such as sea level rise, landslides, floods and droughts due to its dense population and dependence on natural resources. Climate change impacts on infrastructure can lead to severe social and economic consequences by disrupting access to basic services. Mainstreaming climate resilience into infrastructure planning can help reduce these risks through fortifying infrastructure, increasing system capacities, and building in higher elevations. This requires assessing climate hazards and risks, adapting planning policies, technical standards, and financing strategies to account for future climate conditions. However, developing climate resilient infrastructure faces challenges from uncertainties around future climate impacts, a lack of climate information, and misaligned incentives across administrative cycles.

Wind energy; it's place in Wales
This document discusses wind energy and its role in Wales' renewable energy goals. It notes that while energy use in Wales has decreased, consumption continues to increase overall. Currently, renewable generation in Wales comes primarily from wind, hydro, and bioenergy, but the share of UK renewable generation from Wales has fallen in recent years. Barriers such as inconsistent planning policies have hindered growth of renewables in Wales. The document argues that wind energy can help meet Wales' future energy needs through benefits like jobs and community funds, but current policies do not adequately support increasing renewable capacity from sources like wind.
Renewable energy - what's in it for us?
Talk given to Young Planners Cymru on 30th March 2013. Covering renewable energy and its implications for Wales.
Renewables and infrastructure in Wales
1. The document discusses developing infrastructure for renewable energy in the UK and Wales, noting that energy consumption continues to increase while renewable growth is too slow to meet targets.
2. It summarizes that wind is currently the cheapest form of renewable electricity generation, though costs for other technologies are declining as well.
3. Small-scale systems are poised to revolutionize the electricity generation system beyond just solar, moving away from large-scale utilities.
Community energy
This document discusses community benefits from renewable energy projects in Wales. It notes that balancing local and regional needs is important when determining community benefit funds. Examples are given of potential annual funds from onshore wind projects of £620,000 and offshore wind projects ranging from £2,000 per MW for smaller projects up to £6,000 per MW for larger ones. Scotland is highlighted as leading the way in establishing long-term community benefit funds from renewable energy through mechanisms like local trusts. The document concludes that close collaboration between stakeholders and continued progress is needed to maximize community benefits from renewable energy development.

It notes that costs are not always fully accounted for currently and some impacts are difficult to quantify. The author advocates taking a skeptical approach and acknowledges that the transition to renewable energy sources will happen gradually as different actors influence the pace of change.
Biomass to power
This document discusses biomass as a source of electricity in the European Union. It notes that biomass currently accounts for 7.4% of electricity production on average across EU members. The document addresses some challenges with biomass electricity including its relatively low energy density compared to other renewable sources as well as potential competition with food production and biodiversity for land use. It calls for sustainability criteria to guide the industry's growth and challenges relying on potentially inefficient biomass technologies.
Hydro potential in Europe
The document discusses a study by the European Environment Agency (EEA) on the environmental potential for hydroelectric power in Europe. The study analyzed data from the EEA's ECRINS database to determine the technical and environmental potential for hydro, with environmental potential defined as using 0.33 of mean river flow at a capacity factor of 70%. The data was incomplete but improving, and the EEA may revisit their analysis next year with better proxy information to refine their estimates.
Jan 2011 - How does the UK NREAP stack up to other European countries?
The UK has set renewable energy targets to source 21% of its energy from renewables by 2010, 33% by 2015, and 30% by 2020. While the UK has ambitious goals for wind capacity growth and marine renewable development, it lags behind several other European countries in current renewable energy usage per capita, and will need to emphasize the development of solar, heat pumps, and transport alternatives to meet its future targets.
Green power for crisis management
The document discusses using renewable energy for crisis management. It provides some facts about renewable energy sources like solar, wind, hydro, and biomass providing 75% of liquid fuel needs and allowing for onsite production of heat and electricity. It also lists several useful links for information on renewable energy technologies and projects. The document encourages remembering that renewable energy and energy friends can help with remote power needs.

2010 - Environmental impacts of hydropower
This document discusses hydroelectric power potential in Europe. It summarizes that a study by the European Environment Agency (EEA) found the technical potential for hydroelectric power is restricted, but the environmental potential is even more limited after accounting for environmental factors. The study used a database called ECRINS to analyze hydrological data and potential dam sites in catchments. It made assumptions about factors like water flow rates, plant efficiencies, costs, and environmental impacts to estimate potential. While the technical potential is limited, the document suggests focusing on innovating business models to adapt. It also notes that environmental protections like Article 4.7 must be maintained.

The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away
