I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait 'til oil and coal run out before we tackle that.
Thomas Edison, 1931
Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!
William McDonough, Fortune Brainstorm Conference, 2006
I find that the harder I work the more luck I seem to have.
Design is not just what it looks like and feels like. Design is how it works.
Steve Jobs, 1955
Every second, the sun produces about 400 trillion watts of energy. That’s the equivalent of a trillion 1 megaton atom bombs!
The United States consumes 25% of all the world’s energy.
If the air conditioning at the Astrodome in Houston were turned off, it would rain inside the stadium due to the entrance of humid air.
Across America, home refrigerators use the electricity of 25 large power plants every year.
A hot water faucet that leaks one drop per second can add up to 165 gallons a month. That's more than one person uses in two weeks.
An energy-smart clothes washer can save more water in one year than one person drinks in an entire lifetime!
When you turn on an incandescent light bulb, only 10 percent of the electricity used is turned into light. The other 90 percent is wasted as heat.
Every time you open the refrigerator door, up to 30 percent of the cold air can escape.
Every year, more than $13 billion worth of energy leaks from houses through small holes and cracks. That’s more than $150 per family!
Approximately 10.5 gallons of water is used in a dishwasher. Washing the dishes by hand can use up to 20 gallons of water.
Approximately 60% of the water used by households during the summer is used for watering flowers and lawns.
An average home creates more pollution than does the average car.
Most wind power turbines are still installed on land, but the future could lie offshore. Wind speeds over oceans are on average twice as high as over land, making offshore wind parks an interesting alternative, but technically more challenging alternative.
An average wind speed of 14 miles per hour is needed to convert wind energy into electricity.
At the close of 2008, worldwide production by wind turbines was 120.8 gigawatts.
A heavy coat of dust on a light bulb can block up to half of the light.
If every American home replaced just one light bulb with an ENERGY STAR qualified bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars
Americans threw away 38 billion plastic water bottles in 2006.
A million and a half barrels of oil - enough to fuel 100,000 cars for a year - were used to produce the bottles
Electricity itself was still a novelty when Cornell University introduced the nation's (and the world's) first course of study in electrical engineering in 1883. Now, the reach of electrical and computer engineering extends from the nano-scale level of integrated electronics to terrestrial-scale power grids; from single-transistor devices to networks comprising a billion nodes.
