what is renewable energy
What ISrenewable energy?
  • Renewable energies are energies that are located inwater, air and under the ground. Theseenergiesareinfinite.
  • Types of renewable energies: 1)Aerothermalenergy;
  • 2) Geothermal energy;
  • 3)Hydrothermal energy;
government law protocol
Government law Protocol
  • In Latvia there is a law protocol named: «The Renewable Energy Law.»
  • It wasreviewed in 15.02.2011.
  • The law aimsis:To promote local renewable energy economy needs a stable long-term regulatory investment environment for renewable energy.
aero thermal energy
Aero thermal energy
  • Aero thermal energy is the heatthat is in the air.
  • Types of aero thermal energy: 1)wind generators;
  • 2) solar energy.
  • In Latvia we have more than 33 wind generators, that produce about 26 MW a year.
geothermal energy
Geothermal energy
  • Geothermal energy is heat beneath the surface of the land.
  • Geothermal energy is used to:
  • Heat houses.
  • Grow crops.
  • Produce energy.
  • Geothermal pumps are used almost in every country.
hydrothermal energy
Hydrothermalenergy
  • Hydrothermal energy is heat in the surface waters.
  • Types of hydrothermal energy:
  • Water turbines
  • Wave energy converters
  • In Latvia we have a total of 161 hydroelectric stations.
  • The 3 biggest hydroelectric stationsproduce 3039 GW per year.

untraditional ways to get energy
Untraditional ways to get energy
  • Compost heap: Use lime to get the pH neutral(acid pH 0-7, neutral 7, base 7-14)
  • Mulch is made by chipping wood in special wood chippers.
  • Mulch almost always is made from trees that grow in special orchards.
  • You can use mulch: 1)As a fuel.
  • 2)As manure.
  • 3) To reduce the amount of water the soil
