Energy economics is about understanding how we use energy and how much it costs to use energy. Energy is important for keeping our homes warm, our lights on, and for running the machines that make our food and goods. We have to pay for energy, so understanding the economics behind energy use is important for making sure we're spending our money wisely. Energy economics is all about understanding how energy is produced, what it costs to produce, and who pays for it. By understanding energy economics, we can make sure we have enough energy to power our homes and businesses, and help make sure we're getting the best prices for our energy use.
