Thermal (Steam) Turbine Power Plant

1. Heat is made when fossil fuels are burned.

3. The steam makes turbine blades and shaft spin.

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.

4. The generator converts mechanical energy into electrical energy using magnetic fields around a metal conductor.

2. Heat turns water into steam.

solar thermal collector
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.

slide27

Hydropower

Lake Mead has provided water for Hoover Dam since 1935. Does this look like a renewable or non-renewable energy source?

slide28

Coal Mining

Surface mining for coal –

look familiar?

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.

coal burning

Coal Burning

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.

Great Smog of 1952 in London killed 4,075 people. Most victims died from respiratory or cardiovascular problems.

Reno, with an unhealthy layer of smog.

slide30

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.

slide31

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.

tar sands

Tar Sands

The price of oil sands – devastated landscapes in Canada.

nuclear power

Nuclear Power

This is what happens to nuclear waste.

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.
