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. As the two of us started to evaluate the feasibility of such a change, we took on an even larger challenge: to determine how 100 percent of the world’s energy, for all purposes, could be supplied by wind, water and solar resources, by as early as 2030.

Management Thinking Winning the waiting game Winning the waiting game: Insurers' preparations for the new IFRS accounting rules is a Deloitte report written by the Economist Intelligence Unit From The Economist Intelligence Unit Read more The confidence game Jevons paradox The Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. 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]

Solar Panels in Schools Reduce Energy Costs 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.

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. 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.

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.

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.

Germany - 26% of Electricity From Renewable Energy During First Half of 2012 Clean Power Published on July 26th, 2012 | by Thomas Gerke During the first half of 2012, the share of renewable energy sources in the electricity supply has risen significantly in Germany, rising to a sensational 25.97%. That’s a massive increase compared to 20.56%, the percentage during the same period in 2011, and 18.3% in H1 2010. PV-Solar Contribution Increases 47% In total, renewable energy sources produced 67.9 TWh (billion kWh). Rebuilding the Foodshed: Fields of ENERGY Over the coming days, we'll be sharing material from Chapter 4 (Energy) of the latest Resilience guide, "Rebuilding the Foodshed: How to Create Local, Sustainable & Secure Food Systems". This is a heck of a chapter, one that takes a look at the complex relationships between food systems, energy and waste. If you eat food, grow food, use energy, create energy, or make waste, you'll find yourself fascinated. Read Part 2, Read Part 3, Read Part 4, Read Part 5, Read Part 6, Read Part 7

Twine, A Tiny Gizmo That Holds The Internet's Future "In the future, your house will send you a text message to warn you that your basement is flooding." Sounds like the kind of hooey you only hear in those fantastical "future of…" videos, doesn’t it? Not anymore. Two MIT Media Lab graduates have created a "2.5-inch chunk of the future" called Twine that does exactly that, and more, and is available right now. Well, not quite: It will be available in early 2012, thanks to its wildly successful Kickstarter campaign. And the best part about it, the part that surely made that fundraising surge to over $170,000?

Can Crowdfunding Unlock an Off-Grid Solar Revolution? The poorest people on the planet spend more on energy than we do. Surprised? I live in a two-bedroom apartment in Brooklyn and calculated that my roommate and I spend about $850 annually on electricity and gas. This represents 0.5 percent of our combined annual income (before I joined the startup world, that is).
