Energy For Human Use

HOW MANY RESOURCES CAN PRODUCE ELECTRICITY?

what does energy resources mean
What does Energy Resources mean?
  • "Energy Resources" is NOT the same thing as “Forms of energy".
  • "Types of energy" or “Forms of energy” means "kinetic energy", "chemical energy“. Thermal,
  • "Energy Resources" is about ways of getting energy so we can generate electrical power.

Renewable Resources

Non-Renewable Resources

  • Natural resources that cannot be replaced or that can be replaced only over thousands or millions of years.
  • Natural resources that can be replaced over a relatively short period of time.

most of the earth s energy comes from the sun
Most of the Earth's energy comes from the Sun
  • Solar power, that's obvious, but the energy in coal originally came from the Sun too. Prehistoric plants stored the Sun's energy in their leaves, and when they died and eventually formed coal seams, that energy was still there. So when we burn coal (or any fossil fuel), we're releasing chemical energy that was stored in plants millions of years ago.

  • The same goes for Wind and Wave power. Waves occur because of winds, and winds blow because the Sun warms our atmosphere. Warm air tends to rise, and winds are due to other air moving in to replace it.

  • Most power stations burn coal, oil or natural gas to run the generators. Others use uranium, or the flow of water. Electricity is sent around the country using high-voltage power lines. Nearly all of the power we use comes from large power stations, although some places such as isolated farms, or hospitals, have their own diesel generators.

Energy Resources for ELECTRICITY

COAL_, gas and oil are _NON RENEWABLE_ energy sources that are burned to make THERMAL_ energy to boil water. When the water is heated the water molecules will _SPEED UP_ and they space between them will INCREASE_. Soon the water will EVAPORATEand turn to steam. Then, the moving steam is MECHANICAL_ energy to spin a _TURBINE_. The turbine will turn magnets and coiled wire in the _GENERATOR_. This will transform _MECHANICAL_ energy to _ELECTRICAL_energy.
