1. Heat is made when fossil fuels are burned.
2. Heat turns water into steam.
3. The steam makes turbine blades and shaft spin.
4. The generator converts mechanical energy into electrical energy using magnetic fields around a metal conductor.
5. Before reusing, the water must cool. It is pumped to the top of a cooling tower, broken into drops. Up to 2% of water evaporates.

Solar Thermal Collector
These high-temperature collectors concentrate sunlight using mirrors or lenses and are used for electric power production with steam turbine power plants.

Hydropower
Lake Mead has provided water for Hoover Dam since 1935. Does this
look like a renewable or non-renewable energy source?
27
Coal Mining
Coal companies also mine coal from mountains through a process called mountaintop removal mining where the top of a mountain is removed to extract the coal. Waste is disposed in nearby valleys and streams.
Surface mining for coal – look familiar?

Coal Burning
Great Smog of 1952 in London killed 4,075 people. Most victims died from
respiratory or cardiovascular problems.
China’s air pollution has cut life expectancy by an average of 5.5 years in the north of
the country and caused higher rates of lung cancer, heart attacks and strokes.

Natural Gas and Hydraulic Fracturing or “Fracking”
A homeowner in Granville Summit, Pennsylvania, holds up a glass of tap
water containing high levels of methane, a concern for those who live
near fracking sites.

Natural gas fire in San Francisco, CA in 2010. Killed 4 people, injured dozens of others, and leveled 37 homes.
This natural gas rig burning out of control in the Gulf of Mexico caught on fire July 23rd 2013.

Nuclear Power
Following a major earthquake, a 50 ft. tsunami disabled the power supply and
cooling of three Fukushima Daiichi reactors in Japan, causing a nuclear accident on March 11, 2011. All three cores largely melted in the first three days. Nuclear
reactors were leaking into the ocean after this disaster.
This is what happens to nuclear waste.
