Can you save the lightning? That is not renewable resources?
Knowledge point two:The international unit of energy is the Joule, referred to as coke, the symbol is J. Commonly used units are degrees, scientific name kwh,The symbol is kW H. 1kW * h=3.6 * 10^6J.Perceptions of Joule, kwh: an apple from the ground up to the desktop the energy required is about 1J, the flashlight 1 power consumption is about 1J, the microwave oven work 1 hours power consumption is about 1kW H.
Knowledge point:Electricity is a form of energy, which is made up of various forms of energy, which are made by a variety of power plants and various kinds of batteries.A power supply is a device that provides electrical energy, in fact, the conversion of other forms of energy into electrical energy. Power type: wind power, hydraulic generator converts mechanical energy into electrical energy; thermal power is the conversion of chemical energy to electrical energy; solar power is converting solar energy into electric energy; nuclear power is the use of atomic energy into electricity. Battery types are: dry batteries, lead-acid batteries, cell phone battery is the conversion of chemical energy into electrical energy; silicon photocell is the conversion of light energy into electrical energy; solar cells is to convert solar energy into electricity.The electric appliance converts electrical energy into other forms of energy at work. The lamp converts electrical energy into energy and energy; electric fan, trolley, vacuum cleaners, washing machine and the electric energy into kinetic energy; TV, computer power mainly transformed into light and sound; water heater, electric cooker convert electric energy to energy etc..
Electrical energy refers to the ability of electricity to work in various forms (i.e., produce energy). Electric energy is widely used in power, lighting, metallurgy, chemical, textile, communication, broadcasting and other fields, is the main driving force for the development of science and technology, national economy leap.Knowledge of electrical energy (summary)
Electricity is an intermediate product of energy, energy is two. Two times energy is generally not analysis it is not renewable energy. But in a sense, can be regarded as clean energy, energy from the whole process, the production of electric energy generated in the process of environmental pollution, energy could not clean energy constrained environment.
