New Hydropower Laws Could Add 60 GW Of Clean Energy To US Grid

The one thing everyone working on energy issues in America can agree upon is non-existent energy policy action at the national level. But late last week President Obama signed two bipartisan bills that could create a major boost for US renewables generation from an unlikely source – small hydropower.

It’s kind of amazing these bills becoming law hasn’t gotten much attention, since they’re the first real energy legislation to pass Congress since 2009, and could ultimately create 1.2 million green jobs while adding 60 gigawatts of new renewable electricity to the grid.

New Kind of 40% Efficient Solar Farm Gets $90 Million DOE Loan Guarantee to Cogentrix

The largest High Concentration Photovoltaic (HCPV) project in the world is being funded by the DOE with a $90 million loan guarantee for the Cogentrix Alamosa Solar Generating Project. The first 20 years of the electricity it will generate has already been bought under a PPA (power purchase agreement) by the Public Service Company of Colorado. More than 80 percent of its components will be sourced from the United States.

HCPV is new form of utility-scale solar that has barely been developed, but it has great potential because it has almost twice the efficiency of regular solar PV. Cogentrix HCPV is rated at 40% efficient. By comparison, most coal plants are typically rated at 30% efficiency.

The $90 million in funding represents the tail end of almost $40 billion in loan guarantees, loans, or conditional guarantees by the US Department of Energy (DOE) powered by the Obama administration stimulus Recovery Act.

One famously went bad, $0.5 billion to Solyndra. But the more than 40 DOE loan guarantees have

Plant A Tree — Even Wall Street Agrees

A new way to treat wood has trees back in the limelight: a hardwood’s reliability that even a rain forest mahogany tree can love.

Check out the world’s first heavy traffic road bridge made from Accoya® wood. The bridge, located in Sneek in the Netherlands, is “the first wooden bridge in the world that can support the heaviest load class of 60 tons”. At this week’s Wall Street Green Trading Summit, a panel on forestation introduced a new way of thinking about how to deal with destruction of the rain forest.
