There are two ways we get power from water. One way we get electricity is through hydraulic power plants (inside dams). Water falls through pipes. The falling water turns petals on a shaft inside a generators. The other way is through tidal power plants. Tidal power plants are always inside bridges and rely on big differences in the depths of the water between high and low tides. Tidal power plants may never be a major source of power. The only plant built using tidal power is in France.

The wind has been a source of power to do something for over thousands of years. The windmill has been to grind wheat. Although, as the world evolved, the idea was used, and the wheat-grinding windmill evolved to a electricity-producing windmill.

One small/compact way YOU could produce YOUR OWN electricity is by installing solar panels on your roof. They don't cost a lot of money, but could produce enough electricity to keep your power bill down by about 15%.

Other ways we get electricity is from indirect power from nature. You usually use power from fossil fuels ( crude oil, coal, and natural gas). Those generators are rigged to spin a shaft using something with something. Or the other ways would be through geothermal power.

Fossil fuels are burned in different ways for different uses. Coal is burnt for electricity producing, manufacturing (for heating steel, aluminum, etc.), and home heating. Coal is our main source of electricity. Crude oil can be made into different things in a refinery. After coming out of the refinery, the oil can now be used for gasoline (for automobiles), diesel fuel (for cars, trucks, and trains), jet fuel, then kerosene and oil for home heating. Oil can also be burnt for electricity. Natural gas can be used for cooking, bottled gas (for campers and outdoor grills), and home heating. One day we will run out of this major utility and everything that we use it for along with it if we don't conserve this natural wonder

We can get power from geothermal power plants. Some people dig into the earth's crust and put big pipes in the earth at hot spots. Magma under the earth's crust heats up water in underground rivers. The steam travels up the pipes and turns petals on a shaft in a generator. The Geysers (a geothermal power plant) can produce enough electricity to run a large city. There are plans to expand The Geysers. Some geothermal power plant's electricity have to be transported great distances, so geothermal power plants can be very costly.

We need to save and conserve all energy and electricity or someday we may run out of this important resource.
