Electrical energy.
unplug things like the tv
By converting it to electrical energy and then chemical energy through photovoltaic cells and storing in some form of battery or capacitor.
Fuses are overcurrent protection devices. If voltages get extreme they blow to save other components. So yes in a way they detect electrical energy.
1) To save money. 2) To help protect the environment.
Saving energy will (a) save you money, and (b) help protect the planet, since using a lot of energy usually harms the planet.
There are many ways to save energy.Some are:Turn the lights off when you leave a roomPut full loads of clothes in the laundryUse energy efficient appliancesDon't use electrical appliances that muchWear a sweater instead of turning the heat onRemember; These are only some ways to save energy.

Panasonic has a very good exhaust fan that is energy efficient. Any electrical item that has the energy star label on it is energy efficient, which is good for saving money and helping save the environment.
The benefits of using solar electrical power over conventional electric power is that it is renewable, it can save money on conventional electrical bills, and if used in large enough quantities it can even eliminate the need for energy from energy companies.
