อReviewable energy and farming are a winning combination. Wind, solar and biomass
energy can be harvested forever, providing farmers with a long-term source of income.
Renewable energy can be used on the farm to replace other fuels or even sold as a cash
crop. It is one of the most promising and important opportunities for value-added
products in agriculture. It has been said that “anything that can be generated from a
barrel of oil can be generated from biomass. They type of renewable energy technology
used in agriculture depends on the type of energy required, access to the renewable
energy source and the design of agricultural facilities and processes. Solar energy can be
used in agriculture in a number of ways, saving money, increasing self-reliance, and
reducing pollution. Solar energy can cut a farm’s electricity and heating bills. Solar heat
collectors can be used to dry crops and warm homes, livestock buildings, and
greenhouses. Solar water heaters can provide hot water for diary operations, pen
cleaning, and homes. Photovoltaics (solar electric panels) can power farm operations and
remote water pumps, light, and electric fences. Building and barns can be renovated to
capture natural day light, instead of using electric light, solar power is often less
expensive than extensive power lines, making the farm more economical and efficient.
This paper therefore discusses briefly the various applications of solar energy technologies
in agriculture.
