The correct answer is D. All of these.
Solar energy, wind energy, and biogas are all renewable energy resources. Renewable energy resources are those that can be replenished naturally over time. They are a sustainable alternative to fossil fuels, which are non-renewable and contribute to climate change.
Solar energy is the energy that comes from the sun. It can be used to generate electricity, heat water, and power vehicles. Solar energy is a clean and abundant resource that is available all over the world.
Wind energy is the energy that comes from the wind. It can be used to generate electricity, pump water, and power ships. Wind energy is a clean and renewable resource that is available in many parts of the world.
Biogas is a gas that is produced from the decomposition of organic matter. It can be used to generate electricity, heat homes and businesses, and power vehicles. Biogas is a clean and renewable resource that can help to reduce greenhouse gas emissions.
Renewable energy resources are becoming increasingly important as the world looks for ways to reduce its reliance on fossil fuels. They offer a clean, sustainable, and affordable alternative to non-renewable energy sources.
