Energy consumption continues to grow.
The costs of generation and transmission of energy must come down for the increased consumption to be sustainable. Energy must be generated without depleting resources, without causing pollution, and without incurring waste. Transmission of energy too must be efficient. These ideal goals, when realized, would enrich lives, regardless of economic distinction.
A viable solution is the onsite generation of electricity using the photovoltaic (PV) method of converting solar energy directly into electrical energy. The PV method uses semiconductor devices called solar cells. With constant reduction of the cost, this method is the most promising direct current (DC) power source for rich and poor globally. Due to the availability of solar energy all over the world, PV generation is not hostage to the usual geo-political constraints. Thus, it can power an energy revolution just like the information revolution powered by the internet continues to shape our world today…
