Feasibility Assessment: Proposed B.C. LNG Facilities and Renewable PowerClean Energy Canada
Navius Research Inc. and Steve Davis & Associates produced a conceptual design for powering the LNG terminal on the North Coast that would maximize renewables at its production facility and do so reliably, affordably and on schedule—using established commercial technologies. Further, doing so reduces that plant’s carbon pollution by 45 percent, its air emissions - nitrogen oxides - by 70 percent and increases local permanent jobs by 40 percent. The cost for all these benefits? A 1 percent increase in projected sales price of the LNG.
Italy has seen significant growth in solar energy production in recent years. Solar power generation increased nearly 350% from 2007 to 2008. The regions with the highest levels of solar irradiance are Sicily, southern Italy, and Sardinia. To encourage further development, the Italian government offers incentives like "Conto Energia" which pays individuals and businesses up to 75% of the cost of solar installations. These incentives have helped drive strong growth in the solar industry in Italy.
This document proposes a high-return-on-investment wind turbine design that eliminates the need for expensive yaw systems, brakes, and foundations. It would utilize ultra-high lift airfoils optimized for moderate wind speeds and constant cross-section blades that can be mass produced. Initial funding is requested to build 10 pre-production prototypes to test in various locations and demonstrate the viability of the simplified, lower-cost design. The goal is to produce a turbine that pays for itself in under 10 years without subsidies by targeting markets with consistent moderate winds.

Czech energy policy by Milan Šimoník (30.1.2016)bagmaster
This document discusses Czech energy policy and its focus on nuclear energy compared to Germany's Energiewende policy focusing on renewable energy sources (RES). It notes that the Czech government and energy company CEZ claim the country's RES potential is insufficient and new nuclear plants will be needed to avoid power shortages by 2020. However, the document argues the RES potential has not been fully utilized and presents data showing the RES potential could meet 16-42 TWh of electricity demand by 2040, eliminating the need for new nuclear plants. It advocates for a "realistic green scenario" where the Czech Republic significantly increases RES use instead of relying on nuclear energy as its primary energy strategy as envisioned in the country's energy plans.
The Feed In Tariff (FIT) scheme was introduced in the UK in 2010 to provide payments to businesses and communities that generate electricity from renewable sources like solar panels. Under FIT, energy suppliers must pay generators a premium for all electricity produced for 25 years, whether used or not. Additional export payments are made for electricity sold back to suppliers. A 12kW solar system in Sheffield is estimated to generate over £125,000 in FIT payments over 25 years and save over 50% on electricity bills.

This document discusses various paths to market for energy storage technologies. It outlines opportunities for energy storage to be integrated with wind and solar power generation to help manage intermittency issues, including: repowering existing wind farms; allowing wind farm extensions; reducing offshore wind curtailment; providing peak lopping services; and helping to stabilize output from solar PV installations. The document also discusses potential roles for energy storage in supporting industrial energy cost management, microgrids, and innovative operations and maintenance approaches for wind farms.
The document discusses the UK's need to invest in renewable energy due to aging coal and nuclear power stations and its dependence on fossil fuels. It introduces the UK's Feed-in Tariff (FiT) incentive for solar power, wind, and other renewables that provides returns of 6-12% annually over a 25-year contract. It also summarizes Germany's successful solar FiT program and industry. While the UK solar market was initially nervous, installations grew once the FiT rates and contracts were confirmed. The document proposes using solar power to address energy poverty through projects that could reduce tenants' electricity bills by 30-50%.
This document compares the costs of natural gas and solar power. It provides the current price per MMBTU charged by SSGC for industrial customers. It then converts this gas price to a price per kWh, calculating it to be approximately Rs. 17 per kWh. The document estimates the daily energy output and savings from a 1,000 watt solar installation. It calculates that the upfront cost of such a solar system would be paid back in around 4 years based on avoided electricity costs from gas.
On Thursday 19 November 2015, the British Embassy in Paris hosted a second trilateral workshop with French, German and British delegates from the research, government and business sectors to discuss the importance of energy storage.
Shore-to-ship power, also known as cold ironing, involves providing electrical power from the shore to ships while docked in ports to reduce emissions.

Practically Delivering Energy-ReducingTechnology To Optimise Efficiency On T...Andy_Watson_Sim
The document discusses practical ways to improve energy efficiency through retrofits. It recommends:
1) Taking an asset-based approach to retrofits to maximize opportunities and cost efficiency at scale.
2) Integrating suppliers, engineering, and contractors to minimize costs through discounted volumes, optimized space, and reduced risk.
3) Continuously measuring performance using techniques like cumulative sum analysis to identify problems and the effects of efficiency improvements on stable building operations.
This document proposes replacing the conventional diesel generator and battery-based power system used by EthioTelecom with a hybrid system incorporating a fuel cell, microturbine, and DC/DC converter. It analyzes the technical specifications and performance of the system components, models the new system, and compares the costs, emissions, and reliability to the conventional system. The analysis finds that the hybrid system has lower operating costs, reduced emissions, higher reliability, and a payback period of around 6 years, making it a more sustainable option for telecom power in Ethiopia.
The document proposes an alternative technology project to reduce greenhouse gas emissions from a housing construction project in Mexico. The key points are:
1) A construction company is building 10,000 homes that would emit over 108,540 tons of CO2 annually using conventional technology, exceeding Mexico's limit of 25,000 tons.
2) The proposed alternative uses solar panels, LED lights, and solar water heaters, reducing emissions to 24,462 tons annually.
3) This alternative would cost $230.9 million initially but save $158.9 million annually in energy costs while generating $121.1 million annually from selling the reduced emissions credits. The investment would be recouped in 1 year and 9 months

This presentation discusses the outcomes and benefits of the decentralised trigeneration, New York Cities renovation of existing power plants and solar /wind power.
The document discusses energy generation and markets, with a focus on how Peterborough City Council is generating renewable energy, reducing energy consumption and costs, and using the financial benefits to regenerate the city. It summarizes Peterborough's approach of generating renewable energy, reducing energy use, enabling regeneration, reducing carbon, and making and saving money. It then discusses the council's various energy initiatives, including collective switching programs, energy packages, solar PV projects on corporate and residential buildings, and tackling fuel poverty through these programs.
This document discusses optimizing plant electrical efficiency through capturing residual or waste heat. It describes two scenarios: a biogas setup and a biomass setup. A modularized plant design is proposed with four modules: a standard process module, evaporator, optional heat rejection module, and electrical power module. Business cases are presented for installing an ORC system at a UK biogas site and biomass site, showing paybacks of 3.18 and 2.7 years respectively. Contact details are provided for further information.
The document discusses a new report by researchers at the Centre for Alternative Technology (CAT) in the UK. The CAT has a history of pointing towards a sustainable energy future for Britain. Their new report, called "Zero Carbon Britain 2030", describes in detail how the UK could transition to a zero carbon society as early as 2030. The report models how the UK could achieve this transition through steps like rationalizing energy demand, implementing low/zero carbon supply systems, and employing net-negative carbon processes.
The document analyzes the feasibility of installing wind turbines and solar panels at Puffin's new cold storage site to reduce energy costs and carbon footprint. It evaluates installing a 100kW Norvento wind turbine with a 36m tower and 24m blades. Simple cash flows show it would generate 258,717 kWh annually, saving over £46,000 per year in electricity costs. Over 20 years it would have a cumulative positive NPV of over £466,000. Solar options and payback periods are also analyzed for roof mounting.

Editor's Notes
Welcome Who I am Coconuts I’m going to give a brief background to the state of the UK energy market today and in 10 years time Then I’m going to explain about the incentives for renewable energy Then a look at 3 technology types
There are 2 Main Drivers for growing the renewable energy industry in the UK today. The first is Climate change There is global consensus that climate change needs to be tackled. The EU has set targets to reduce emissions, which are a 20% reduction in carbon emissions and 20% reduction in energy use (i.e energy efficiency) and a 20% use of renewables by 2020 across Europe as a whole The UK has its own targets to reach in agreement with the EU which I will briefly cover.
The EU Renewable Energy Directive requires the UK to obtain 15% of its total Energy Consumption from renewable sources by 2020 and the UK has committed to reducing its carbon emissions by 34% as well. The Govt has set out The UK Low Carbon Transition Plan National strategy for climate and energy This covers all energy sectors, electricity, heat, and transport. Shortfalls could be subject to heavy penalties (although the 2009 directive doesn’t state this implicitly) Currently the UK is only at 3% of its target for 2020 – 2 nd from last after Malta………… To meet the 15% we need to have 30% of our electricity generation coming from renewables. We need a 12 fold increase on a renewable heat production and a 7 fold increase on transport (i.e biofuel).
2nd Driver- Security of Supply
The Position Today we have A balanced mix of GAS, COAL AND NUCLEAR with very little supported by renewables.. If we look forward to the future in 2020 It is proposed that we have a balance between gas, coal and renewables – but we have been a net importer since 2004 so presents a big problem to security. Nuclear is ALL BUT GONE Meanwhile, power demand/consumption continues to increase
The UK is potentially facing a huge energy crisis This is not scaremongering it is fact. 9 oil and coal fired power stations are due to close by 2015 because they have come to the end of their design life 4 nuclear power stations are due to close a year later. The regulator predicts blackouts by 2016 National Grid forecasts we will have to import three-quarters of our gas by 2015
This slide shows our actual consumption of energy, projected future demand and the source of home produced fuel. We became net importers of energy in 2004. BOEPC stands for barrels oil equivalent per capita ENERGY USE CONTINUES TO INCREASE whilst our HOME GROWN UK PRODUCTION FALLS AWAY A SERIOUS WIDENING GAP until NEW NUCLEAR COMES ON STREAM IN C> 2025 but even this is in doubt because coalition are proposing no subsidies are being offered to kick start nuclear Renewables have role in filling this gap in a country that has excellent renewable sources of energy So what's the UK Govt doing about it?
Various incentives have been introduced: Non Fossil Fuel Obligation introduced in the 1990’s Renewable Obligation Certificates under the Renewable Obligation Order in 2002 FIT’s RHI These Govt Incentives often referred to as govt subsidies but really INCENTIVES introduced by GOVT and NOT SUBSIDY THAT THE GOVT PAYS.
Shows the changing incentives for Wind Energy
Betz law states that we can only capture 59% of the power in the wind. In reality, most turbines at best manage 40% and smaller turbines are doing well to produce greater than 30%
But wind turbines can fail – blade breaks
PV Planning we hope will be easy but nobody really knows – low impact compared to wind – but might be an issue on valuable arable land Technology is very well proven and established (small amount of degradation over time, but only 0.5% per annum Outputs – downside is outputs are low. 2MW wind turbine produces the same as 25 acres of PV! Returns are at best marginal, but a safe bet over the long term

Different turbine types for different flow and heads. Cross flow turbines typically work well with low head schemes but equally the Archimedes reverse screw turbine is gaining popularity and works well with low head sites were other small scale hydro schemes wouldn’t be economically viable. Critical aspect is the consideration of the head and flow rate – with high heads sites a Pelton turbine would be a better choice as it has a high generating potential. Capital costs of the development must be considered, and are very site specific, with large variations in costs when compared against Wind turbines and PV.
Very low capital costs have made the development of a crossflow hydro turbine at this existing mill site very attractive. Attracts 22.8 pence per kWh
Attracts 20.8pence per kWh Has suffered from the impact of drought restrictions almost halving output.
High Head scheme Actual output April 2009 – March 2010
PLANNING – conflict between Govt trying to push for rapid development of renewables whilst at the same time legislating for more localised planning decisions. Often difficult, with many failures for large scale projects. Some of the best areas of the country for wind or solar are no go areas, because of land designations such as AONBs, National Parks, Heritage Coastline etc. The impact of PV on high grade agricultural land may be a consideration as well as visual such as Poly tunnels. GRID – The UK IS NOT SUITED TO LOCALLY EMBEDDED GENERATION. Large scale developments often require £Millions to get grid connection due to capacity issues. Smaller scale developments become uneconomical due to costs of connection. The DNOs (district network operators) are slow to respond to connection and feasibility queries and will often take advantage of developers in regards to grid reinforcement. Network plans are difficult to obtain and DNOs can take 6-9 months to respond to technical issues. TECHNOLOGY – renewable energy generation is in many cases in its infancy. Wind, PV and Hydro well established on large scale developments, but smaller scale suitable technology has not been proven in many instances. Failures of plant are common place and real output figures instead of theoretical outputs are difficult to obtain. FEED STOCK – often underestimated how difficult to secure long term contracts, without which lending can be a problem. Fluctuating prices also make economic viability difficult to establish FINANCE – the lack of liquidity in the market for any form of development has hit renewables just as hard as other main stream developments.
