Renewable energy
Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable . About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass, which is mainly used for heating, and 3.4% from...

 (ESMAP), exploitation of the country’s significant wind potential alone could cover more than the country’s current total energy needs.

Investment costs

Investment costs for renewable energy technologies in Colombia were estimated in 2005 as follows:
Energy source Technology Cost (US$/kW)
Large hydro Reservoir (dam) 700-1,700
Solar PV Photovoltaic solar systems 5,000-10,000
Wind (on shore) Electricity generation 800-1,200 (large scale)
up to 3,000 (small scale)
Pump 1,500-4,000
Geothermal Electricity generation 3,000-5,000 (small scale)
1,500-2,500 (large scale)
Biomass Direct combustion 2,800-5,000

Hydropower

With 70 percent of the country’s power generation, hydropower is a very important national energy source. The total large hydropower potential for Colombia is estimated at 93GW, with an additional 25GW of small hydropower (<20MW)

Wind

The wind regime in Colombia is among the best in South America. Offshore regions of the northern part of Colombia, such as in the Guajira Department, have been classified with class 7 winds (over 10 meters per second (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 Guajira Department—enough to generate sufficient power to meet the national demand almost twice over. However, the country only has an installed capacity of 19.5 MW of wind energy, tapping only 0.4% of its theoretical wind potential. This capacity is concentrated in a single project, the Jepírachi Wind Project, developed by Empresas Públicas de Medellín (EPM) under a Carbon Finance

Solar

Colombia has significant solar power
Solar power
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available...

, with 6 kWh/m2 of radiation. Of the 6 MW of solar power installed in Colombia (equivalent to about 78,000 average-size solar panels), 57 percent is distributed in rural applications and 43 percent in communication towers and road signaling. Solar systems can be very suitable for applications in rural areas, where energy demands are dispersed and modest and grid connection is often more costly (UPME 2005).

Geothermal

The former Colombian Institute of Electrical Energy, today IPSE, and the Latin American Energy Organization have identified three areas with geothermal power

Biomass

Colombia has a great biomass power potential from agricultural residues (banana, coffee pulp, and animal waste). Its annual biomass power potential is estimated to be over 16 GWh, which is still less than 0.1% of current electricity production. The potential is distributed as follows:
  • 11,828 MWh/yr from agriculture residues
  • 2,640 MWh/yr from bioethanol
  • 698 MWh/yr from natural forest residues
  • 658 MWh/yr from biodiesel
  • 442 MWh/yr from planted forest residues


The region of Urabá in the north of the Department of Antioquia has approximately 19,000 hectares of banana plantations, producing more than 1 million tons annually. It has also been estimated that approximately 85,000 TOE/yr could be produced from the 190 million m3/yr of biogas generated from coffee plantations, equivalent to 995,000 MWh.

In addition, the landfills in the four main cities in Colombia (Bogotá, Medellín, Cali, and Barranquilla) are estimated to have the potential to provide for an installed capacity of 47 MW (0.3% of current installed capacity).
