Единственным фактором, который порой останавливает людей от установки электрических тёплых полов в своей квартире, порой является необходимость тратить электрическую энергию на их работу. Однако этот фактор уже практически потерял свою актуальность, так как производители подобных систем существенно снизили данный показатель и создали специальные устройства, позволяющие регулировать работу обогревателей по времени. Эти устройства хорошо программируются на […]

River Hum: Hydroelectric Energy
What Is It, and How Does It Produce Electricity? For the past several hundred years humans have put beavers to shame. We have built more than 845,000 dams around the world to block the natural flow of rivers. And these are not the meandering creeks that beavers dare attack. No. We humans have corralled many […]
Second Time Around: Energy Recapture
What Is It, and How Does It Produce Electricity? America has been called a “throwaway” society. Research has shown that we “throw away” most of our energy. Over 50 percent of all the energy we consume is wasted—thrown away—mostly as waste heat up a smokestack or out a tailpipe instead of performing useful work. But […]
A Swim in the Balmy, Briny Sea: Ocean Thermal Energy Conversion (OTEC)
What Is It, and How Does It Produce Electricity? The oceans of our planet—not the land—are the great storage shed for the sun’s radiant energy. Each day the oceans absorb solar energy (heat) that is the equivalent of 250 billion barrels of oil. If we could convert only 0.1 percent of this energy into electricity […]
Electricity in a Box: Batteries and Energy Storage
What Is It, and How Does It Produce Electricity? Batteries are devices that store energy. They don’t create energy. They just hold it for future use. We use batteries to power electrical equipment when it is impossible or inconvenient to plug into the grid. The problem is that electricity from a battery is much more […]
“Catch a Wave, Dude!”: Ocean Wave Energy
What Is It, and How Does It Produce Electricity? Wind skims across the surface of the ocean and transfers some of its energy into the water, pushing up waves. The longer the wind blows, and the harder it blows, the bigger the waves grow. The bigger the waves become, the more energy they absorb from […]
Micro-Might: Nanotechnology
What Is It, and How Does It Produce Electricity? Nanotechnology is poised to usher in a revolution that could change our lives and social structure far more radically than computers, the Internet, automobiles, or even electricity itself have. Almost like a towering tsunami, nanotechnology is poised to crash over all aspects of modern life and […]
Rollin’, Rollin’ with the Tide: Ocean Tidal Energy
What Is It, and How Does It Produce Electricity? The tide rolls in; the tide rolls out—-just like clockwork, every day of every year. That regular rise and fall of the ocean’s surface that we call “the tide” is created by gravitational tugs from the moon and the sun. You don’t notice the effect of […]
