Renewable and Non-renewable Energy Resources

by Kevin Stark There are two major categories of energy: renewable and non-renewable. Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The advantage of these non-renewable resources is that power plants that use them are able to produce more power on demand. The non-renewable energy
