Answer:
Solar energy, biogas, Electric energy.
Explanation:
Although solar energy and biogas are types of renewable energy that guarantee little impact on nature, the best alternative to generate electricity at home is still electricity. This is because solar energy can only generate electricity when the sun is available, that is, there would be no electricity at night and during winter. In addition, installing solar panels is very expensive. The price would also be a problem in the use of natural gas, since its use is usually very expensive. In that case, the best option would be electricity.
However, we cannot forget to point out that the combined use of the three energies would be great for a home, since it would bring savings and reduce the environmental impact.
