Geothermal technology uses energy in the earth's crust to heat water and buildings.
In London, West German cities and New York, hundreds of plants burn 4 million tons of refuse each year, heat water, produce steam, and supply electricity.

At least the effect on your wallet will be the same as driving your car with solar energy in fact, most people use more energy to heat water than they do driving their car.
FORBES: Natural Gas Could Be The Next Big Thing For Cars, But Probably Won't Be
If you have a run of cloudy days and there is not enough solar heat to completely heat your water -the water heater will come on and heat water just the same as it always has.
FORBES: Gassing Up: Why America's Future Job Growth Lies In Traditional Energy Industries
They did bigger things, like putting solar panels on the roof to heat water, as well as smaller things like teaching residents that their iPhone chargers, if left plugged in the wall after the iPhone is charged, continue to consume electricity.
Secondly, when considering end-to-end efficiency, it is much less energy-intensive to heat water by direct use of natural gas on-site, rather than by using that natural gas to first make electricity that is used to heat water because of the large conversion losses at power plants.
Ivanpah is a solar concentrator project, using fields of mirrors, known as heliostats, to concentrate sunlight onto a solar receiver on top of a tower. (This project when finished will include 173, 000 heliostats.) The concentrated sunlight is used to heat water, generating steam which is used to turn a traditional turbine and generator to produce electricity.
FORBES: Google Invests $168 Million In BrightSource Energy Solar Plant
The 59-acre (24 hectare) site will also boast a solar thermal hot water system to pre-heat the water for the heating system, and a biomass boiler that will provide heat using locally-sourced wood chips.

Following the devastation wrought by Superstorm Sandy, millions across the northeast struggled without electricity, heat and water as temperatures plunged.
FORBES: It's Time To Upgrade The Entire World's Infrastructure
In the simplest terms, a fuel cell combines hydrogen and oxygen in a process that releases electricity, heat and water.
In Rizhao, a coastal Chinese city of 3 million people, more than 90% of households use solar power to heat their water, Lovins said.
It can be used to run an internal combustion engine in a car or power one using a fuel cell, with heat and water as the only emissions.
ECONOMIST: Chicken feathers could provide a high-capacity store
As long as circulating water continues to remove this heat, pool water temperature is maintained well below boiling, typically below 120 degrees Fahrenheit .
Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).
And consider the electricity that needs to be generated to move and heat all that water.
The latest cooling tricks, including big copper heat sinks and water-filled pipes, are not keeping up.

The bulk of methane use today is to heat buildings and water.
FORBES: Natural Gas Could Be The Next Big Thing For Cars, But Probably Won't Be
Without an active removal of decay heat, the reactor was adding heat to the water faster than it was taking it out, and the temperature was rising.
FORBES: Explainer: What Caused The Incident At Fukushima-Daiichi
Until about two weeks ago, the family had been living without heat or hot water, relying on electric heaters to keep warm and showering at friends' homes.
It's important to remember that even as the effect of Superstorm Sandy recedes from the news, there are still devastated areas that are without electricity, heat or hot water.
