Climate Change: The Need for a More Consistent Baseline and Immediate Action

The UN climate conference in Lima set the stage for Paris in 2015. Next year’s accord is to provide a working, albeit not a final, answer to the question: Is it possible to keep global warming at or below the 2 degree Celsius limit? This limit is considered the boundary beyond which the negative climatic, economic and social consequences of climate change are thought to become intolerably severe and potentially irreversible.

Brazilian Bank Raises $408 Million for Renewable Energy and Water Projects

The Brazilian bank Itau Unibanco Holding SA raised 1.05 billion reais ($408 million) to finance renewable energy and water treatment projects.

Seven Reasons Cheap Oil Can't Stop Renewables Now

Oil prices have fallen by more than half since July. Just five years ago, such a plunge in fossil fuels would have put the renewable-energy industry on bankruptcy watch. Today: Meh.

Carbon Nanoballs Can Transform the Renewable Energy Supply

Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

Want to Buy a Used German Power Plant? Shipping Is Included

Germany’s utilities, battered by the country’s shift to wind turbines and solar panels, would be glad to sell you a power plant on the cheap. They’ll even pack it up and ship it to another country.

California's Clean Tech Industry Best in US for Jobs and Investment

California’s bet on green energy is paying off, with clean technology companies creating more jobs and investing more money than competitors in any other state.

Renewables Beat Natural Gas, Provide Half of New US Generating Capacity in 2014

Ending a year-long race that had been nip-and tuck every month, renewable energy sources cumulatively provided more new electric generating capacity in 2014 than did natural gas.

Carpe Diem: Low Oil and Gas Prices Could Be a Clean-Energy Opportunity

The recent dramatic plunge in oil and natural gas prices, to their lowest level since the global recession in 2009, has some observers worried about the effect on clean tech. Conventional wisdom has it that renewables have a tougher time competing when fossil fuels are cheap, making grid parity (in the case of natural gas-fired electricity) more elusive for solar and wind power.

The Promise of Clean Energy Student Entrepreneurs

Cleantech investing has taken quite a hit in recent years. Last year, CBS News highlighted the “cleantech crash” on U.S. primetime television, and Bloomberg New Energy Finance, a Bloomberg-owned energy data firm, has tracked the multi-year decline in cleantech investing. However, there are additional trends that tell another side of the cleantech story and suggest innovation and hope for a low-cost, low-carbon future are far from gone.

Former FERC Chief Jon Wellinghoff Speaks Out on Grid Security and Distributed Generation

In a previous article, I had a conversation with former-CIA chief Jim Woolsey to discuss one of America’s greatest national security vulnerabilities, its power grid. The issues that Woolsey has been concerned with for over a decade has been the ease in which a terrorist group or other actor (think North Korea for example) could attack the grid and plunge the country into darkness for months, if not years. And if that seems far-fetched, just recall how a tree limb fell in Ohio in 2003 and blacked out the entire Northeast and part of Canada for several days.
