In 2007, Colombia had 28.1 MW installed capacity of renewable energy (excluding large hydro), consisting mainly of wind power.HydropowerThe total large hydropower potential for Colombia is estimated at 93 GW, with an additional 25 GW of small hydropower (<20 MW).Solar energyColombia has significant solar power resources because of its location in the equatorial zone, but the country sits in a complex region of the Andes where climatic conditions vary. The daily average radiation is 4.5 kWh/m2, and the area with the best solar resource is the Guajira Peninsula, with 6 kWh/m2 of radiation.Wind energyThe wind regime in Colombia is among the best in South America. Offshore regions of the northern part of Colombia, such as in the Guajara Department, have been classified with class 7 winds (over 10 m/s). The only other region in Latin America with such high wind power classification is the Patagonia region of Chile and Argentina. Colombia has an estimated theoretical wind power potential of 21 GW just in the Guajara Department.
