The world runs on electricity. Demand for electron power in emerging economies is often 3-4 times greater than demand for oil. Because the old model of the electricity grid does not seem adequate in meeting the new demands of the 21st century, many energy pundits argue that access to electricity is the world’s biggest strategic energy issue.

The Obama-Biden comprehensive New Energy for America plan will: Watch the Video Provide short-term relief to American families facing pain at the pump Help create five million new jobs by strategically investing $150 billion over the next ten years to catalyze private efforts to build a clean energy future. Within 10 years save more oil than we currently import from the Middle East and Venezuela combined. Put 1 million Plug-In Hybrid cars -- cars that can get up to 150 miles per gallon -- on the road by 2015, cars that we will work to make sure are built here in America. Ensure 10 percent of our electricity comes from renewable sources by 2012, and 25 percent by 2025. Implement an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050.

The book Sustainable Energy – Without the Hot Air by David J.C. MacKay is a unique case among all of the current publications on this topic. If every author and decision maker involved with climate change and energy issues would take this book as a starting point before making any claims or proposals, the world would be saved a huge amount of discussion-energy, energy-to-disentangle-confusion, and energy-spent-on-fruitless-efforts.

USA Energy goals: Cheap, plentiful energy Clean energy with low environmental impact Reduce carbon emissions by 50% Reduce reliance on OPEC by 50% Achieve global energy leadership

Nearly 50% of global electricity supplies must come from renewable energy sources in order to cut CO2 emissions in half by 2050, the International Energy Agency (IEA) says in its latest study, “Deploying Renewables: Principles for Effective Policies.”

If hydrogen is introduced into the energy system, the cost to reduce one unit of CO2 decreases by 4% in 2030 and 15% in 2050, implying that hydrogen is a cost-effective option for the reduction of CO2

Growth in the renewable energy industry is set to reach more than US $250 billion by the year 2017 with the electric car, sustainable cities, non-U.S.-based energy firms, geothermal energy and the greening of the shipping industry helping to lead the way. That's the prediction made by Clean Edge in its Clean Energy Trends 2008 report released on Wednesday.

The simultaneous onset of climate change and the peaking of global oil supply represent unprecedented challenges for human civilisation. Global oil peak has the potential to shake if not destroy the foundations of global industrial economy and culture. Climate change has the potential to rearrange the biosphere more radically than the last ice age. Each limits the effective options for responses to the other. The strategies for mitigating the adverse effects and/or adapting to the consequences of Climate Change have mostly been considered and discussed in isolation from those relevant to Peak Oil. While awareness of Peak Oil, or at least energy crisis, is increasing, understanding of how these two problems might interact to generate quite different futures, is still at an early state.

It does not happen often that I agree with the American Enterprise Institute but Steven Hayward’s analysis of the “real cost of tackling climate change” in the Wall Street Journal of 28 April is spot on: an 80% reduction of greenhouse gas emissions by 2050 will have dramatic implications for our way of life. Hayward has at least the courage (which cannot be said for our politicians) to tell the public what this 80% cut will mean for citizens’ daily lives. In not one political document have I ever seen a serious impact assessment of the 80% target. The fear of being the bearer of bad news is one which characterises all policymakers (even the ones who know that the climate crisis will hit hard).

The three primary, longer-term objectives for the nation's energy policy should be: reduce greenhouse gas emissions to a level consistent with a world-wide goal of global climate stabilization (assumes curbing U.S. CO2 emissions by 60-80% from current levels by mid-century); eliminate U.S. energy imports (i.e., oil and natural gas - now 58% and 15% respectively), while reducing overall use of oil and natural gas; phase out the current generation of nuclear power while substantially curbing the production and consumption of fossil fuels, by increasing the use of energy efficiency and making a transition to sustainable, environmentally safer renewable energy sources.

Yesterday, the European Parliament approved by overwhelming majority the "Thomsen Report" on the Roadmap for Renewable Energies in Europe. Crucial for the future of solar thermal: the call for the adoption in all Member States of renewable heat obligations, at least in new buildings and those undergoing major renovation.

Most of the technologies that could reduce greenhouse gases are not only expensive but would need to be embraced on a global scale, scientists say. Many projections for 2030 include as many as 1 million wind turbines worldwide; enough solar panels to cover half of New Jersey, massive reforestation; a major retooling of the global auto industry; as many as 400 power plants fitted with pricey equipment to capture carbon dioxide and store it underground; and, most controversial, perhaps 350 new nuclear plants around the world.

Unique in its scope, the 18-month study of global energy to 2030 involved more than 350 experts from diverse backgrounds and organizations—the majority of them from outside the oil and gas industry.
