renewable energy and distributed generation




Distributed generation reduces the amount of energy lost in transmitting electricity because the electricity is generated very near where it is used, perhaps even in the same building. This also reduces the size and number of power lines that must be constructed.

The electrical charge goes through high-voltage transmission lines that stretch across the country. It reaches a substation, where the voltage is lowered so it can be sent on smaller power lines. It travels through distribution lines to your neighborhood.
