Describe four sources of farm energy.

1. Solar energy: Solar panels can be used to harness the sun's energy and convert it into electricity to power farm operations. This renewable energy source is becoming increasingly popular in agriculture due to its sustainability and cost-effectiveness.

2. Wind energy: Wind turbines can be installed on farms to capture the energy of the wind and convert it into electricity. Wind energy is another renewable source that can help reduce reliance on fossil fuels and lower energy costs for farmers.

3. Biomass energy: Biomass, such as crop residues, animal manure, and wood chips, can be burned to produce heat and electricity for farm operations. This organic material is a renewable energy source that can help reduce waste and provide a sustainable energy solution for farms.

4. Geothermal energy: Geothermal heat pumps can be used to harness the natural heat from the earth to provide heating and cooling for farm buildings. This renewable energy source is highly efficient and can help reduce energy costs for farmers while also reducing greenhouse gas emissions.
