Given the rapidly rising cost of energy it goes without saying that we all would realistically like an energy-efficient home, and if there was a chance to get some energy for free then that seems to be a complete no-brainer. So is this a pipe dream or is there a route to this golden goal?
The solution is electricity. Electricity can be generated from many sources, stored and then turned into energy or heat. To generate our own electricity we can install solar photovoltaic (PV)
