Green technologies to watch
« on: April 21, 2009, 08:00:19 am »
From a technology perspective, things have changed a lot since the first Earth Days of the 1970s.

After barely moving for decades, there's been a surge in innovation in energy the past five years, fueled both by society's growing interest in clean energy and by the technology revolutions in other industries, like IT and biotech. That has expanded the definition of clean energy from solar and wind to many other areas.

"We are in a new era of energy innovation," declared Daniel Yergin last week at a forum on clean-energy policy at the Massachusetts Institute of Technology.

Yergin is someone who should know. As the author of "The Prize," a book about the history of the oil industry, and co-founder of Cambridge Energy Research Associates, he advises CEOs of giant oil and gas firms on energy strategy. Like many people in green tech, he's not a typical 1970s-era tree hugger but a hard-boiled business man who sees technology change driven by economic, environmental, and national security reasons.

Innovation "runs across all sectors and it has a very strong climate change focus," Yergin said. "Clearly, one of the areas of major innovation is the nexus of transportation, smart grid, and renewable and alternative" energy.

Which technologies specifically have a good shot at making the biggest impact? As part of our Earth Day 2009 coverage, we try to handicap technologies that bear watching.

The list:
Utility-scale solar. Despite all the press around solar energy, its contribution to national electricity generation is barely a blip. But after a multi-decade hiatus, utility-scale solar power is back on the agenda, led in the U.S. by sun-blessed California's renewable energy mandates.

Solar with Wind Generators work combined on a home it gives 99% coverage with that 1% being in the worst days of winter. That could be handled by a clean running natural gas generator.. Its been done in Wisconsin at a Welders shop and home..
But we probably wont see that in City area's till the Electric companies stop making it hard to make conversions. City Centers and States are coming around with trying to make it easier.

Cars can be built to get 100 MPG on a large scale but its still not being done due to pressure by the oil companies... I wont name names.. But thats been a big hold back for the past 8 years.

I swear I'm gonna go out and buy up Bags and Bags of L.E.D.s, plus Diodes and start building my own light bulbs
