It’s time we stopped wasting time with brain dead energy saving mantras and got on with the real task of building a clean energy infrastructure so we can use far, far more electricity.[read more]

combined heat and power

Combined heat and power (CHP) is an underutilized tool that could have a huge impact on industrial energy efficiency. But how do the benefits of CHP stack up against building new wind, solar, or natural gas facilities?[read more]

mid-Atlantic offshore wind

Atlantic Wind Connection plans to enable the Atlantic Coast to use off-shore wind efficiently. When completed, the AWC will be able to carry as much as 7,000 MW of offshore wind energy to consumers along the US East Coast.[read more]

carbon tax

Many U.S. residents strongly believe that the U.S. needs to substantially reduce its carbon emissions in the near future. Is it time for the U.S. to implement a national carbon tax?[read more]

thinking toward 100% renewables

Even those in favor of renewable energy have been known to debate how much of our power it can provide. But at the conference, the question was not whether we can get to 100%. Instead, speakers asked, How do we get there?[read more]

oil-free Sweden?

The oil crisis in the early 1970s forced Sweden to embark on a quest for alternative energy sources. In 1970, oil accounted for 77 percent of Sweden’s energy, but by 2003 that figure fell to 32 percent.[read more]

Some think solar and other renewable energy sources are not yet ready for prime time. But nothing could be farther from the truth. In fact, we have the technology to get 100% of our energy from renewable sources.[read more]

natural gas

A glut of cheap natural gas could shelve investments in renewable energy and could encourage consumers to use more energy, slowing the conversion to more efficient appliances, motors, and energy-smart equipment.[read more]

high-voltage supergrid

The piecemeal way that the grid is being reinforced today is not compatible with a future supergrid incorporating renewable energy sources. This post examines an alternative layout for new HVDC connections for a future supergrid.[read more]

smart grid investment

Two cities in California are leveraging innovative financial programs to help fund adoption of both energy efficiency and renewables generation technologies, spurring technology markets.[read more]

Obama declared his confidence his nominees will help achieve his goals of energy independence, more clean-energy jobs, tackling climate change, and economic growth.[read more]

The Energy Efficiency and Renewable Energy agency (EERE) has announced a roadmap workshop for enhanced geothermal. It is inviting a select — small — group of subject matter experts to take part in this roadmap workshop in order to help develop a plan for how the country can proceed in developing its dry rock geothermal resources and...[read more]

I’ve just been forwarded this message from DOE: On June 19th, the United States Senate, by voice vote, confirmed Cathy Zoi to be the Assistant Secretary for Energy Efficiency and Renewable Energy This is a terrific piece of news.  To explain why, I’m going to reprint below my March post “And Obama gives the best clean energy and...[read more]
