How is thermal energy useful
WebWhenever the cost of gas starts burning holes in our wallets, we start paying closer attention to the development of alternative energy technology. Right now, one of those up-and-coming technologies is thermal technology, which uses one of the most common forms of energy: heat.. To understand the technology, we have to know a little about … WebBut this isn't very useful because we are unlikely to encounter extremely low temperatures and so it would be difficult to extract all that energy. Remember that heat always flows from hot to cold. Useful energy in water. Your calculation shows that a temperature change of 49 degrees C will be an energy change of 57 KW-hr. But what is that exactly?
