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
