Hydropower

Hydropower
Hydropower is a clean renewable energy source. Snow and rainfall, creating streams and rivers, renew the source. Buying Guarantees of Origin from hydropower guarantees that the renewable energy consumed is from this source. Historically people have used rivers for agriculture and to power watermills and sawmills for example. Today, rivers are re-directed through hydro generators […] Read more …

Wind power

Wind power
Wind power has become increasingly common worldwide over the last decades. The production cost of wind turbines has decreased and the technology has rapidly evolved. Buying Guarantees of Origin from wind power guarantees that the renewable energy consumed is from this source. Wind power production is typically divided into two main categories; based Onshore or […] Read more …

Solar power

Solar power
Solar power production converts sunlight into electricity. It is one of the fastest growing renewable technologies and is playing an increasingly important role in the future global electricity generation mix. Buying Guarantees of Origin from solar power generation guarantees that the renewable energy consumed is from this source. Solar power is complicated to produce, but […] Read more …

Geothermal energy

Geothermal energy
Geothermal energy captures the heat from two to three kilometers under the earth’s surface where water meets heated rock and turns it into steam. Steam is led from boreholes to turbines inside the powerhouses of geothermal energy plants, transforming thermal energy into electricity. Read more …

Bioenergy

Bioenergy
After hydro and wind, bioenergy is an important renewable energy source in the European electricity mix. Biomass is any organic decomposable matter from plants or animals available on a renewable basis, such as wood, plants, waste, garbage, landfill gases and alcohol fuels. Steam turbines or gasifiers generate electricity from biomass. Read more …
