...Harvard Students for Clean Energy estimated in their position paper for the proposal that $10 from every undergraduate would pay for 4 million kilowatt hours (kWh) of electricity—equal to 25 percent of the College dorms’ yearly energy consumption, or the yearly production of one “state-of-the-art wind turbine...
...happening. Shanghai, for example, has trumpeted its "Green Culture" campaign, which has filled the city with grassy parks and perched flower boxes upon highway dividers. But energy-efficient measures have not been a priority of "Green Culture," even though the city this year forecasts a 2 million-kilowatt energy shortfall. Shanghai's skyscraper boom boasts only a handful of green buildings?structures that consume up to 70% less energy than normal, according to the U.S.-based National Resources Defense Council...
Quincy succeeded in purchasing TRCs amounting to a little more than two percent of its annual electricity usage, at a one-time cost of $399. This comes out to a premium of one cent per kilowatt-hour on top of the retail rate of electricity of roughly five to 10 cents per kilowatt-hour. This simple calculation yields some huge insight—if the University were to supply all its electricity using renewable energy, it would have to either purchase TRCs or invest in a wind farm of its own. Quincy’s Wind Project combines both TRCs...
...millions of Americans learned two important lessons: that it is possible to spend an entire evening at home without watching TV and that we should all have backup batteries for our cell phones. For those who need a better contingency plan, this portable fuel-cell generator provides a kilowatt of continuous power for eight hours on a single tank of environmentally correct hydrogen. The AirGen is a tad bulky (about the size of a mini-fridge), but you can roll it under a desk. Unlike a gas-powered generator, it emits only water vapor and heat, so it's safe...
...system has been enacted in 36 states to rectify that inequity. Under the plan, called net metering, a homeowner's electrical meter simply rolls backward whenever the house is feeding electricity to the grid instead of pulling it down, reducing the bill at the same price per kilowatt hour the power company charges...
