10 Technologies to Save Us

Expect to see a lot more of these...Popular Science has an interesting special section geared around various alternative energy technologies. The piece details how many different options we can explore:

1.) Wind - the price of wind energy has dropped 85% in the past twenty years. Imagine if this administration actually tried to help out.

2.) Enhance the energy grid's efficiency (ie, move smaller power generation closer to a source)

3.) Hybrid cars - if all American cars were switched to plug-in Hybrids, oil consumption would drop 70-90% overnight

4.) Ethanol - only this country could look to a process (corn) that makes things worse. Sugar, cellulosic, that's where we need to go

5.) Solar - two things need to happen - improve energy efficiency (currently only 15-30%) and make it portable (no, not watches)

6.) Hydrogen power - already twice as efficient as gas combustion engines

7.) Ocean - this was awesome. Portugal will soon start powering 15,000 homes; tidal currents are 10 to 40 times as energy dense as wind

8.) Geothermal - tap the earth's internal heat...although knowing us, we'll find a way to turn it off

9.) Biomass (waste) - 1500 cows can produce 1.8 million KW of energy

10.) Negawatts - turn out the lights when you leave the room dammit!!!
