Renewable energy sources are sources of energy that is (7) - - - - replenished through natural processes. These resources are often also referred to as alternative or (8) - - - -energy, mainly (9) - - - - they are a fuel option that can replace conventional (10) - - - - fossil fuels. Fossil fuels, like oil and coal, produce energy when they (11) - - - -, but their supply is limited because they don’t naturally replenish on a short enough timescale for humans to use. Renewable energy sources are (12) - - - - because they have a very limited negative environmental impact when compared to fossil fuels.
