A Plan to Power 100 Percent of the Planet with Renewables

A Plan to Power 100 Percent of the Planet with Renewables
In December leaders from around the world will meet in Copenhagen to try to agree on cutting back greenhouse gas emissions for decades to come. The most effective step to implement that goal would be a massive shift away from fossil fuels to clean, renewable energy sources. If leaders can have confidence that such a transformation is possible, they might commit to an historic agreement. We think they can. A year ago former vice president Al Gore threw down a gauntlet: to repower America with 100 percent carbon-free electricity within 10 years.

Electricité verte - Certificats verts Observ'ER présente la quatrième édition du baromètre des filières renouvelables électriques en France. L'ambition de ce travail est de réunir en un seul outil un ensemble d'indicateurs énergétiques, socio-économiques et industriels qui, regroupés et analysés, présentent une photographie hexagonale détaillée de tous les secteurs. On y retrouve les énergies renouvelables électriques les plus développées comme l'éolien, le photovoltaïque, l'hydraulique, la biomasse solide, le biogaz et l'incinération de déchets, mais également les secteurs en devenir comme la géothermie, les énergies marines et le solaire thermodynamique. Une attention toute particulière a été portée à la dimension territoriale en produisant, chaque fois que cela était possible, un détail régional de l'état des filières suivies. Pour télécharger gratuitement le baromètre 2013 des énergies renouvelables électriques en France connectez-vous. Le baromètre est disponible en téléchargement dans son intégralité ou par chapitre.

Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher).[3] As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History[edit] The Jevons paradox was first described by the English economist William Stanley Jevons in his 1865 book The Coal Question. At that time many in Britain worried that coal reserves were rapidly dwindling, but some experts opined that improving technology would reduce coal consumption. Cause[edit] Elastic Demand for Work: A doubling of fuel efficiency more than doubles work demanded, increasing the amount of fuel used. See also[edit]

Solar Panels in Schools Reduce Energy Costs | SunPower The West Sonoma County Union High School District (WSCUHSD) had been hit hard by budget cuts and needed a way to save money and address rising energy costs. A solar power project could do both, and with voter approved bonds, the school district received the capital improvement funding to make a solar project a reality. SunPower’s 2010 Commercial Dealer of the Year, RGS Energy, won the school district contract, and in only four months, the school district had a combined 834kW of solar power at three high schools. SOLAR BRINGS GENERAL FUND RELIEF In the five years up to 2011, the West Sonoma County Union High School District (WSCUHSD) had cut 10% of all teaching positions and 32% of administrative and district office staff positions. SUNPOWER SOLAR PANELS MAXIMIZE ENERGY, MINIMIZE LAND USE The WSCUHSD wanted a solar project that offered the best possible return on investment, but the district had limited space for solar panels.

“Green Nukes” An Important Climate Change Mitigation Tool Adam Curry interviewed Curt Stager, the author of Deep Future: The Next 100 Years of Life on Earth for his Big Book Show. During the interview, Curry and Stager spent several minutes discussing the potential for “green nukes” to be an important climate change mitigation tool. Aside: Adam Curry interviewed me four years ago about Adams Engines; he has been interested in new nuclear power plants for a long time. There are many terrific reasons to favor the rapid development of nuclear fission technology. For some odd reason, possibly having to do with certain brands of political ideology, many nuclear professionals are reluctant to emphasize that last feature. There are also many people employed in nuclear-related activities who are energy agnostics. I have a different point of view. As Curt Stager and other researchers like him have determined, the material will be suspended in our atmosphere and affecting our climate for at least 100,000 years.

How to power America with renewables on the cheap: Build a shit ton of wind and solar capacity America could be powered almost entirely with wind turbines and solar systems by 2030 at a cost comparable to what we’re spending for dirty power today, a new study finds. The necessary approach would surprise most people, and it would generate enough economic activity to make any capitalist drool: Build, build, build … and then build some more. From Midwest Energy News: The analysis … challenges the common notion that wind and solar power need to be paired with fossil fuel or nuclear generators, so utilities can meet electricity demand when it’s not windy or sunny.The paper instead proposes building out a “seemingly excessive” amount of wind and solar generation capacity — two to three times the grid’s actual peak load. For the study, published in the Journal of Power Sources, researchers used a model to evaluate the cost effectiveness and reliability of tens of billions of combinations of renewable energy generation and storage capacity.

What Role Should Government Play in Energy Production? - Energy and Environment Experts The best role for government in energy production may be in the R&D side in the national labs, universities, and so forth. But the choice of what to invest in should be done via a double blind review system by real experts in the relevant fields. The government might also think about developing energy research and application prizes, but these should also be as independent of the usual sordidness of real political economy as possible. Most large government programs to subsidize new technologies for energy or whatever have the lobbyists hunting about for the big game of government largess. Solyndra was no different. They were in lobby overdrive and that should have been a give-away that something was not right in Solyndraville. When all of the facts of the Solyndra case are in the open, if they ever are, we might find that the story is far more complex (surprise, surprise) than presented in the media recently. Why do I keep using quotes around “green energy”? Change can be good.

Publications: Magazines and Newsletters by Fatih Birol Page 2 of 3 Power Sector Investment Needs To meet the expected growth in electricity demand through 2030, cumulative investment of $10 trillion in power-sector infrastructure will be needed - equivalent to 60% of total energy-sector investment. The power sector in developing countries will require more than half of the global investment, exceeding $5 trillion. Generation is the largest single component of total power infrastructure investment. Refurbishment of existing power plants over the next 30 years will need investment of $439 billion. In OECD countries, where networks are more developed, most network investment will be needed for refurbishment and replacement of existing equipment. Challenges in OECD Countries Power-sector investment now accounts for less than 0.5% of GDP in most OECD countries, and that figure is expected to drop to an average of 0.3% over the next three decades.

PRESS RELEASE: Potential of Renewable Energy Outlined in Report by the Intergovernmental Panel on Climate Change — SRREN PDF Version Abu Dhabi, 9 May 2011 – Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows. The findings, from over 120 researchers working with the Intergovernmental Panel on Climate Change (IPCC), also indicate that the rising penetration of renewable energies could lead to cumulative greenhouse gas savings equivalent to 220 to 560 Gigatonnes of carbon dioxide (GtC02eq) between 2010 and 2050. The upper end of the scenarios assessed, representing a cut of around a third in greenhouse gas emissions from business-as-usual projections, could assist in keeping concentrations of greenhouse gases at 450 parts per million. This could contribute towards a goal of holding the increase in global temperature below 2 degrees Celsius – an aim recognized in the United Nations Climate Convention's Cancun Agreements. The six renewable energy technologies reviewed are: Notes to Editors Useful links:
