Why is agriculture important?
Agricultural systems are requiring an increasing amount of energy to cope with the current and projected growth in demand. Unfortunately, increased use of nonrenewable energy has a detrimental impact on our environment. In today’s world, where the effects of climate change are very real and fast approaching, it is crucial to use sustainable processes for agriculture. Renewable energy can contribute greatly to transform the methods of food production, thereby having a positive effect on food security too.
Can wind power be used for agriculture?
The power of the wind can also be harnessed for agricultural purposes . According to the UCUSA, farmers can plant crops and graze livestock right by a wind turbine’s base, as each turbine only uses less than half an acre of space. In a previous article, we’ve written about Taylor farms, the leading producer of value-added produce and healthy fresh foods in North America. In an effort to be more sustainable, the farm now utilizes a three-part wind, solar, and cogeneration energy system at its facility in Gonzales, California. While not all farmers can afford these advanced energy systems or even single wind turbines, wind power cooperatives have started to form in order to spread and maximize the benefits of wind power.
Is solar energy a viable alternative to natural gas?
Solar energy provides a feasible alternative. Experts at UCUSA write, “The amount of energy from the sun that reaches Earth each day is enormous. All the energy stored in Earth’s reserves of coal, oil, and natural gas is equal to the energy from only 20 days of sunshine.” Plants have used solar energy to produce food since the beginning of time, and so it stands to reason that the agricultural industry can benefit from the practically unlimited power of the sun.
