Human power is the rate of work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles , but body heat is also used to do work like warming shelters , food, or other humans.
Electricity generation is the process of generating electric power from sources of primary energy.For utilities in the electric power industry, it is the stage prior to its delivery (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.
The environmental impact of electricity generation from wind power is minor when compared to that of fossil fuel power. [58] Wind turbines have some of the lowest global warming potential per unit of electricity generated: far less greenhouse gas is emitted than for the average unit of electricity, so wind power helps limit climate change .

Waterfalls provide spring water for humans, animals and plants for survival and habitat for marine organisms. The water current can be used to turn turbines for hydroelectric generation. The ocean is an example of a natural resource. Ocean waves can be used to generate wave power, a renewable energy source.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. [citation needed] These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted.
Fire is an example of energy transformation Energy transformation using Energy Systems Language. Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. [1] In physics, energy is a quantity that provides the capacity to perform work (e.g. lifting an object) or provides heat.
For example, in America in 2012 there were some 78 million dogs, 86 million cats, and 3.5 million rabbits. [55] [56] [57] There is a tension between the role of animals as companions to humans, and their existence as individuals with rights of their own. [58] Many animals are hunted for sport. [59]
