2.  It can be used to produce electricity, heat houses and warm water.  When we go renewable energy sources over the solar energy would decrease air pollution by 90%.  Estonia would not be able to use solar energy in winter, but other times it would be good

4.  Nowadays wind energy is technically well developed and is competitive  Small wind turbines give individuals and businesses for energy security and independence of fossil fuels for power cuts, and with large price fluctuations.  Estonian beach, open sea, and Lake Peipsi are enough windy to build wind farms and therefore are our wind energy resources quite large.  Wind randomness is not yet possible to ensure a stable electricity production capacity, which makes it unsuitable for use as the only source of energy.

6.  Water is an environmentally friendly means of power generation, does not violate the air as greenhouse gases.  Estonia can not only depend on hydropower, but it is a good way to reduce our dependency on oil shale energy.

8.  Biomass perhaps forest, scrub, reed beds and agricultural energy.  Biomass supply is high - half of Estonia's territory is forested.  Biomass recovery time is comparable to the human lifespan.
