Wind and solar energy are examples of *renewable resources* Unlike coal or gasoline which is used up when it is burned, wind and solar energy are always there to use again and again. The wind will always keep blowing and the sun will always keep shining (except for a cloudy day) so they are renewable resources.

Answer from: surfer89

Wind and solar energy are examples of renewable resources

Further Explanation

Available resources in nature can be classified into renewable resources and non-renewable resources.

Renewable resources These are energy sources that are replenished naturally within short periods of time. Renewable resources are more convenient and desirable to use because they renew faster and therefore there is continuous regeneration with use. Renewable resources are therefore, inexhaustible as they cannot be exhausted permanently as they are continuously supplied by nature. Examples of renewable resources include; wind, solar, water, biomass and geothermal. Solar energy is a renewable resource as the sun will shine through out. Wind energy is another renewable resource as wind cannot be stopped from blowing. Geothermal energy is also a renewable energy that generates heat from the earth. Other examples of renewable resources include bio-fuels, fuels that are obtained from living organisms. Nonrenewable resources. These are resources that are available only in limited supply. Nonrenewable resources include; coal, natural gas, oil, and nuclear power. Nonrenewable cannot be replenished like renewable resources and are exhaustible as they are not continuously replenished by nature. Nonrenewable resources are scarce resources and are not abundantly available in nature. Additionally, they are costly and not easily available. Despite the importance use of nonrenewable resources, they have various negative impact on the environment, such that they pollute the atmosphere by releasing various pollutants in air when burned.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 x 10^6 kg of coal each day, and the heat of combustion of coal is 3.3x 10^7 j/kg. the steam that drives the turbines is at a temperature of 300° c, and the exhaust water is at 37° c. (a) what is the overall efficiency of the plant for generating electric power? (b) how much thermal energy is exhausted each day? (c) what is the change in entropy of the universe for this heat engine? (d) using the same heat reservoirs, what is the maximum possible (carnot) efficiency for a heat engine?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
