Renewable Energy

Renewable energy sources like wind, solar, geothermal, hydrogen, and biomass can potentially play an important role in the future of our nation.  The Department of Energy and Natural Resources is committed to encouraging the development of renewable sources of energy. 


Light is only a fraction of the energy produced by the sun.  The sun also emits an enormous amount of energy in the form of radiation.  Solar energy systems are able to absorb this energy and convert it into usable forms of energy.  Electricity can be produced directly through photovoltaic cells and panels or indirectly through the production of heat.  Solar radiation can be converted to thermal energy through flat-plate collectors or more advanced concentrating solar collectors including parabolic trough collectors, power towers, and dish systems.

Another natural source of energy in our environment is wind.  Wind energy systems harness the kinetic energy of the wind for conversion into a usable form of energy.  Humans have been harnessing the power of the wind for thousands of years.  The power of the wind was used to explore the world in sailing ships and boats.   The same wind has been used for less mobile applications such as milling and pumping, as well.

Humans began converting wind energy into electricity around the end of the 19th century A.D.  Today, wind power is widely being used to drive generators for the production of electricity.  The wind can be used to provide power to the grid or even produce electricity locally in remote locations where grid interconnection does not exist.

Geothermal heat is the energy contained within the Earth.  This energy can be tapped into to provide clean renewable energy capable of providing baseline power.  The most common geothermal technology being used in Louisiana is the ground-source heat pump.  Ground source heat pumps can often provide significant efficiency improvements over the air-source heat pumps and air conditions normally used in Louisiana.

Ethanol and biodiesel provide alternatives to petroleum based fuels.  These alternative fuels can be produces from renewable, domestic resources.  Louisiana has a diverse resource base which can be exploited to produce them.  Estimates show that Louisiana could produce 18.7% of its transportation energy needs from biofuels using Louisiana resources if the entire crop production is utilized for giofuel production, one-half of the Conservation Reserve Program CRP) land is utilized for energy crop production, and all of the cellulosic component of municipal solid waste is converted to ethanol.

Net Metering

Louisiana law requires all utilites to offer net metering to customers that produce electricity using solar, wind, hydropower, geothermal, and biomass resources.  Net metering is available for residential systems up to 25 kilowatts and commercial and agricultural systems up to 300 kilowatts.

Louisiana Public Service Commission
The Louisiana Public Service Commission is responsible for rule-making relative to statewide net metering.

Louisiana Revised Statute 51:3063 Net Energy Metering
The current statute authorizing Net Energy Metering

Act 653 of the 2003 Regular Legislative Session
Authorized the use of net energy metering in Louisiana

How much renewable energy do we use?
Americans used renewable energy sources - hydroelectric, solar, wind, geothermal, and biomass - to meet about 9% of our total energy needs in 2012, according to the U.S. Energy Information Administration
