The energy consumption needs of technology

As late as 1993, high-tech paraphernalia like computers, printers and video games had a negligible effect on power usage. Today, it's estimated to account for more than 13 percent of a typical household energy budget. By 2020, it could be as much as 25 percent

Tip for saving energy in the home

Replacing an electric water heater with a solar model can reduce water heat costs by 50 to 80 percent every year - and over the 20-year life of the equipment, more than 50 tons of carbon dioxide emissions will be displaced.

Geothermal energy in the u.s.

Geothermal energy currently provides more than 2,700 megawatts of electricity nationwide - the equivalent of three nuclear power plants, or enough to power more than 3.5 million homes. A geothermal power plant emits no nitrogen oxides, very few sulfur dioxides and 1,000 to 2,000 times less carbon dioxide than a fossil fuel plant.

Why laughing gas isn't funny any more

It is used in surgery and dentistry for its anaesthetic and analgesic effects, where it is commonly known as laughing gas due to the euphoric effects of inhaling it. It is also used as a means to enable short periods of extreme high performance in automobile internal combustion engines by introducing extra oxygen into the intake charge which in turn allows a greater amount of fuel to be added and converted into energy and thereby greatly increasing the power produced by the engine. Nitrous oxide is present in the atmosphere where it acts as a powerful greenhouse gas.

The efficiency of converting sunlight to electricity in pv cells

The company SunPower in 2008 announced 22% efficiency converting light to electricity. Current high-performance panels, on average, convert about 20 percent of the light that strikes it into electricity. Conventional silicon solar panels convert about 14 to 17 percent of light.

The theoretical maximum is around 26 to 27 percent, although some have said it could go slightly higher.
