There are sever types of lower costing energy sources: There is biomass energy, solar energy, wind energy, geothermal energy, wave energy, and hydroelectric energy. All of these sources are renewable or are available in amounts that cannot be depleted significantly or easily. Each type of energy source has advantages and disadvantages, but overall they are the perfect options to replace fossil fuel consumption with more earth-friendly, renewable energy sources.
