The idea of personal planes may conjure up dark visions of Blade Runner, but the first batch of two-seater aircraft to fly on electricity rather than fossil fuels could reach more than a dozen buyers by year's end.
And if some fans of experimental air travel have their way, that's a step closer to a gridlock-free future when relatively ordinary folks will hop to work in small, carbon-neutral planes.
A cozy crowd of several dozen engineers, venture capitalists, and members of clean-tech companies plotted the potential at the Electric Aircraft Symposium held Saturday in San Francisco, sponsored by … Read more
Greenhouse gas emissions from data centers rank higher than the countries of Argentina and the Netherlands and right behind airlines, shipyards, and steel plants.
Those comparisons were compiled by consulting firm McKinsey & Company and the Uptime Institute, which on Wednesday published a report on the worsening picture--environmentally and economically--of energy consumption from data centers.
McKinsey called for the creation of a metric that combines the energy efficiency of a data center facility with the utilization of IT gear that runs in data centers. When combined, the financial impact of data centers' energy bill will become more clear and … Read more
That ancient, inefficient heating/air conditioning system in your building might be worth something someday.
Pacific Gas & Electric CEO Pete Darbee said in a briefing with reporters Tuesday that the utility is working with government officials to see if there is a way to create a fund that gives building owners financial incentives to replace old compressors, pumps, and other building equipment with new, energy-efficient versions.
Building owners want to get rid of this old equipment, he explained, but the capital requirements are a big hurdle. The program could be structured in a way so that it could be … Read more
SAN JOSE, Calif.--Washington lawmakers aiming to green both the Capitol dome and the laws made beneath it are turning to Silicon Valley for inspiration while pledging to help renewable energy start-ups get off the ground.
Some Democrats in the House of Representatives fear U.S. policies aren't combating global warming quickly enough. But they hope that they can at least "green" the Capitol complex enough to call it the world's first carbon-neutral legislative body within the year.
"We're making a difference and we're going to change the world," said Rep. Zoe … Read more
Proposals to cool Earth by injecting the atmosphere with sulfate particles would deplete the ozone layer and have "perilous effects" on the planet, according to a paper to be published Friday.
As concerns grow over climate change and global warming, large-scale efforts to alter the planet's climate through geoengineering are being taken seriously by academics.
But a study performed by the National Center for Atmospheric Research (NCAR) cautioned that more research is needed before so-called geoengineering efforts are pursued.
It specifically raised the alarm over the idea of regularly sending sulfate particles into the stratosphere to reduce … Read more
MENLO PARK, Calif.--Back and forth, back and forth. That's the idea behind WaveRoller.
The company, based in Espoo, Finland, says it has devised a way to generate electricity from waves without buoys or other floating devices, the mainstay of other wave power companies.
Instead, the company wants to plant oscillating fiberglass/steel plates on the sea bed. Waves rolling in push over the plates, which rebound after the wave passes to only be knocked down by another wave. The back-and-forth motion of the plates drives a piston and creates hydraulic pressure. The pressure ultimately gets fed to a … Read more
Maybe I shouldn't come to the office anymore. Working from home would treat the planet better, according to the American Electronics Association.
The trade group issued an Earth Day report Tuesday encouraging employers to expand telecommuting, partly to help cut carbon emissions and use of electricity. Among its arguments:
If everyone who could perform a job remotely did so just 1.6 days per week, $4.5 billion worth of fuel would be spared. That would prevent the release of 26 billion pounds of carbon dioxide each year, according to the Environmental Protection Agency.
Nearly half of workers commute … Read more
With Earth Day upon us again, CNET News.com green reporters sat down and selected five leading companies in five different clean technology categories. Here are the ones to watch in the recycling realm:
1. GreenFuel Technologies: Large oil companies and many academics favor capturing carbon dioxide, turning it into a liquid, and storing it underground. Politically, though, that's a tough sell.
GreenFuel, with a pedigree from Harvard and the Massachusetts Institute of Technology and millions in venture funding, wants to feed captured carbon dioxide to algae, and then turn the algae into biofuel. The company is still fine-tuning … Read more
With so many "green" options appearing on everyday products, navigating the marketplace can be tricky if you're attempting to green your life.
Home Depot stamps efficient lightbulbs, low-toxic paints, and other goods as "Eco Options." SC Johnson sells Windex certified by Greenlist, the company's internal effort to reduce toxicants in its product line. Canon labels printers as "Generation Green."
Environmentalists may applaud corporate efforts to sell fewer polluting and poisonous goods and services. But some consumer watchdogs warn that the proliferation of green claims will confuse or mislead shoppers, and prefer that … Read more
