Energy for People • Energy for Enterprise • Energy for Life
Electricity is a necessary, although not sufficient, requirement for modern economic and social development. Electricity opens the door to a host of technologies that promote education, public health, and economic development, such as emissions-free light, refrigeration, and communication devices. Without electricity, communities are unable to participate in the benefits of modern advances and are left isolated and literally in the dark.... |

What is Power? What is Energy?
Power, given in watts (W), kilowatts (kW) or megawatts (MW) is a rate of energy use. By anology, power is equavalent to the rate at which a car travels such as miles per hour (mph) or kilometers per hour (kph).
Energy, given in watt-hours (Wh), kilowatt-hours (kWh) or megawatt-hours (MWh) is a quantity that can do useful work, such as light up a lightbulb. By analogy, energy is equivalent to the quantity of miles or kilometers travelled by a car.
Appliances consume energy, not power, so we are most interested in energy produced and consumed over time.
To calculate energy produced by a generator, you multiply the power of the generator by the time of production: Energy = Power * Time. For example, blueEnergy's turbine produces 1 kW of power in a 13 m/s wind. During one hour of production at this rate, the turbine produces 1 kWh of energy (1 kW * 1 hour = 1 kWh).
Similarly, to calculate the energy consumed by an appliance, or load, you simply multiply the power rating of the appliance by the time of consumption. For example, a 13 W light bulb running for 80 hours will consume approximately 1 kWh (13 W * 80 hours = 1,040 Wh ~ 1 kWh).
