Year in review: Green tech grows flush with green
Investment in energy technologies sped up in 2007, touching heavy industries and consumer products.
Green tech grows flush with green
Venture capitalists strayed further from the comfortable confines of Internet and biotech investing and plowed $2.6 billion into clean-tech start-ups during the first nine months of 2007, which compares with $1.8 billion in all of last year.
Solar technologies and biofuels netted the biggest catches, with other areas such as
The question of whether this is an overheated investment
In the meantime, many new technologies, once dismissed in the days of cheap fossil fuels, are being actively pursued because of high energy prices and environmental concerns.
One of the most viable technologies is solar thermal, where heat is produced by reflective troughs or mirrors to drive electric turbines. Start-up Ausra announced that it received $40 million in financing and has plans to build
But even the dirtiest of fuels is getting its clean-tech treatment.
One of the biggest deals in 2007 was a
In other nitty-gritty sectors, building materials has emerged as an area of innovation.

Outside of big industry is a budding green consumer movement, which has picked up steam as more people become aware of global warming and the growing variety of eco-conscious products.
Despite complaints about
That consumer green streak goes right into the home, where many people are looking to lower their utility bills.
One of the best places to see just how green homes can be was at the
But for all the activity and excitement of how technology can help address environmental problems, the year is finishing with a tinge of trepidation in the green-tech sector, at least for some. The details of a much-fought-over energy bill, which could have a substantial impact on many industries, remain in flux as the year comes to an end.
And like all investment cycles, many new green-tech companies will fail. That may not be just because they don't "execute" their business plans. The technology has to work, too, and that may take a few years to sort out.
2007 Highlights
'Power plants' in the basement heat up
Combined heat and power system sized down to the average home packs on-site power generation and high energy efficiency.
IBM sees green in environmental tech
Big Blue is going green with an initiative that focuses on environmental technologies and services.
Is clean tech a bubble?
Yes, says CNET News.com's Michael Kanellos--but the nutty excesses of the Internet bubble may not come around for this one.
Energy start-ups see IPOs ahead
Will 2007 be the year for energy efficiency companies? Two start-ups are banking on it.
Saving wind power for later
Start-up General Compression looks to commercialize concept for storing electricity generated by wind turbines using compressed air.
Wal-Mart launches solar-power program
Retail giant's pilot projects will generate 20 megawatt hours per year of solar power at 22 stores in California and Hawaii.
New solar technology hits snags
Companies hoping to sell an inexpensive solar technology have had to delay commercial production of their products or change their product line.
Testing the waters for clean tech
Sensicore, which marries IT and water management, is one of the few clean tech start-ups planning an IPO.
Cellulosic ethanol: A fuel for the future?
Emerging techniques for making fuel from lumber by-products carry high hopes and some concerns.
To clean coal, start-up GreatPoint makes gas
Reviving 1970s-era technology, an ambitious company says it can turn dirty coal into cleaner natural gas.
Solar thermal plants go back to the future
Start-up Ausra nabs $40 million in venture capital to build utility-scale solar power plants, an idea that is again gaining traction.
Cutting solar panels' high price tag
Industry luminaries will meet this week at the annual Solar Power 2007 to celebrate booming business. But high costs remain a barrier to wider adoption.
IBM aims to salvage silicon for solar industry
Erase those old circuits and you've got some silicon for solar panels. Big Blue hopes the technique will take off with chipmakers.
Serious Materials gets $50 million to get serious about manufacturing
As expected, the eco-friendly building material maker gets millions to start volume production.
Google to enter clean-energy business
Search giant earmarks hundreds of millions of dollars with the goal of generating a gigawatt of clean energy that's cheaper than coal.
