You may not be able to see the emissions in Mona Miri’s photographs, but you can see where they’re coming from.

The agency will unveil the new rules as early as today—expect this one to get ugly. Fast.

As Americans, we’re conditioned to think big. Big houses, big cars, big screens. Big, centralized power plants that blast energy to our big cities and big suburbs. But there’s a compelling argument to be made for breaking with that paradigm, and starting to think smaller. Of course, that applies to all of the above, but let’s focus on power generation….Read the full story on TreeHugger

Venture capitalists, cleantech executives, and technology experts are optimistic about continued growth for cleantech. With the recession and a clear message from voters, projects requiring billions from taxpayers and/or large customer capital expenditure (capex) are out. Energy efficiency with large and fast ROI is growing rapidly. Distributed solar is outpacing large power plants including utility-scale solar. Smart grids with billions of nodes are the backbone for our future.

“In the U.S. alone, over $2.8 billion of PC power is being wasted every year.”
We’ve written many times about easy power management strategies for computers. Whether it is for your computer at home or for thousands of computers in an office building, there’s no reason not to take advantage of power-saving settings. Everybody wins: you get a smaller electricity bill, and less pollution is produced by power plants. The most recent example of putting this in practice comes f…Read the full story on TreeHugger

Boiler at Middlebury College; The Independent/ Trent Campbell

Mason Inman at National Geographic News is excited about large-scale use of wood as fuel. Looking at Middlebury College’s new biomass boiler and generator, he writes:

Trees suck CO2 out of the air as they grow and then release roughly the same amount of CO2 when they’re burned in the advanced power plants, said Jack Byrne, d…Read the full story on TreeHugger

More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electrici…Read the full story on TreeHugger

75% of our electricity goes into buildings, and much of that runs air conditioning. The entire system is built to try and cope with the peak loads that come in summer. TreeHugger has covered ice storage systems before; they simply make ice at night, when electricity is cheaper and it is cooler, so it is easier to make, and then run air conditioning during the daytime when it is hot and electricity is in short supply. This can knock the peak off the demand curve and significantly reduce the need for new power plants.

But we learned In the Calmac Booth that it can have another significant benefit: It can act as a battery for wind power….Read the full story on TreeHugger
