electricity
INGOCAR is a developmental concept for a 5 passenger car with a hydraulic drive system in place of a conventional powertrian. With the weight reduction this offers and other efficiencies in the systems, the designers say their vehicle could get 170 mpg.
AT&T has just announced a USB-based telephone charger that does not pull electricity from the wall when it's not charging a phone. I don't know about you, but my charger is plugged in 100% of the time. That charger pulls a tiny amount of energy from the wall 24 hours a day 365 days a year. Multipy that by 100 million chargers in America and there's probably at least one coal-fired power plant in America dedicated entirely to that wasted power.

Usually when you read about concentrated solar power, it's referring to some large project destined for the Mojave Desert, but Syracuse's Center of Excellence in Environmental and Energy Systems (SyracuseCoE) has set out to prove that this technology can be used in smaller, colder settings.
Yesterday, Colorado's state legislature finalized a bill to increase the state's renewable energy standard to 30 percent by 2020.
While the focus continues to be on expanding means and methods for generating electricity from renewable sources, the limits of the existing grid to handle that generated power and distribute it to where it is needed are beginning to show.
Energy savings of 99% over previous methods probably sound like snake oil. But some math geeks have been able to find a way so that computers can use only 1% of the energy (and the time) necessary for some tasks.
Sweden's energy minister, Maud Olofsson, announced yesterday that the country would install 2,000 wind turbines over the next decade that would add to 10 terawatt hours of clean energy per year.
The country is also aiming to have 50 percent of its electricity come from renewable sources by 2020. To reach that goal, Sweden will be adding another 15 TWh of renewable energy from sources like solar power and biofuels in addition to the wind power.
