This document analyzes the potential for roof-mounted solar photovoltaics (PV) to meet Olympia's electric demand. It aims to test assumptions about PV in the Northwest and review renewable energy options like PV. The authors hypothesize that Olympia has significant PV potential, particularly downtown roofs, though some areas may be less feasible. National Renewable Energy Laboratory software will estimate power from full roof coverage. Economics will compare PV costs to the true social costs of fossil fuels. Results may change assumptions about PV and show its contribution to Olympia's energy future. Sunny, south-facing roofs are expected to be most economic, while shaded or east/west facing roofs less so. Approximately 10% of

Smart long-term regulation and planning is needed to guide Australia's energy transition and reduce high consumer prices.
Solar energy
Solar energy is obtained from the sun's radiation and can be converted into useful forms of active or passive energy. Active solar energy uses equipment like solar cells to convert sunlight into electrical energy for homes, while passive solar energy uses strategic window placement for natural sunlight heating. Solar panels convert light energy to electrical current through silicon or thin-film crystals, with individual electrons becoming excited and moving freely to produce current. While solar energy has advantages like being renewable, clean and requiring little maintenance, disadvantages include high upfront costs and reliance on sunlight availability. Overall solar provides a sustainable and pollution-free alternative to non-renewable fossil fuels and carries risks of nuclear energy.

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:

Olympia, WA's Solar Potential
- 1. Olympia’s Potential for Roof- Mounted Photovoltaics by Nicholas Acorn and Spencer McLane-Higginson
- 2. Our Question: • How much of Olympia’s electric demand can be met by rooftop-mounted solar photovoltaics (P.V.)?
- 3. ….And could the implementation of P.V. be cost-effective when compared to the true cost of fossil fuels?
- 4. Motivation: • Inspired by the Department of Energy’s Solar Cities program, which estimated the potential of solar P.V. for NYC. • To test assumptions about P.V. in the Northwest. • It is important to review the potential for renewable energy technologies like P.V. if we want to transition from using fossil fuels. Do photovoltaics have potential in Olympia?
- 6. What factors decide the suitability of P.V. for a given area? • Efficiency • Solar resource • Economics http://inhabitat.com/solar-panel-roof-tiles/
- 7. www.NREL.gov
- 9. Economics • Astronomically high prices in the space race • In 1956 a one-watt cell costed $286 www.army.mil/article/37602/Early_Signal_Corps_satellite_programs_rememb ered
- 10. Hypotheses: Primary: Olympia has a potential roof-mounted P.V. resource that can make a significant contribution to the city’s energy needs. Alternative: Only parts of Olympia, like downtown, have enough potential to generate a significant amount of energy from roof-mounted P.V. Another alternative: P.V. can generate a significant amount of energy but is more expensive than an alternative renewable energy resource. Null: Olympia has a poor P.V. resource that cannot generate a significant amount of energy.
- 11. How do you estimate the power that could be produced if all of the rooftops in Olympia were covered in solar modules? -IMBY software developed by the National Renewable Energy Laboratory
- 13. Different areas call for different uses of IMBY
- 14. Compare to the true cost of fossil fuels • Each kWh from coal releases about 2.3 lbs of CO2 (cdiac.ornl.gov/pns/faq.html). • The IPCC found the mean social cost of carbon to be $40/tonne. That’s a little more than a penny/kWh of coal power. • Transalta’s Centralia plant has a social cost of $450 million per year.
- 15. Contribution • Will have a better sense of the contribution P.V. technology could make in the future • Will see how people’s assumptions hold up in the face of in-depth analysis, and help to change those assumptions appropriately
- 16. Expected Outcomes • Sunny areas with south-facing roofs will be the most economic. • Wooded areas and roofs facing east, west or south will be less economically feasible. • A significant fraction (~10%) of Olympia's power could be met by P.V. power.
- 17. Thank You! • http://media.treehugger.com/assets/images/2011/10/solar-panel-sunset.jpg
Editor's Notes
- NW power plan-Efficiency is the most cost effective low hanging fruit.
- Efficiency is less important then Cost/wattReaching theoretical limitP.V is more efficient in the NW then in the Sw different typesdis
- 18 GW of P.V installed7.4 GW installed last yearIntroduce insolation (KWH/m^2/yr)-http://www.renewableenergyworld.com/rea/news/article/2011/03/new-record-for-german-renewable-energy-in-2010??cmpid=WNL-Wednesday-March30-2011
- IMBY software, developed by the National Renewable Energy Laboratory
- Estimate rooftop solar potential by sampling 10% of each land type (residential, apartment complexes, farms, industrial, etc..)Find power density (W/m2)Apply power density to the rest of the land area.Add together the estimated power potential of all the land use types.
