A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

Hydraulic power. Hydraulic power, also called Fluid Power, power transmitted by the controlled circulation of pressurized fluid, usually a water-soluble oil or waterâglycol mixture, to a motor that converts it into a mechanical output capable of doing work on a load.
Hydropower, or hydroelectricity, is electricity generated by the force of moving water in the penstock [8] of a hydropower unit. Turbines are used to capture the kinetic energy of water by converting it to electricity as the falling water spins the turbine.uick Facts. 1  Hydropower is a renewable, efficient, and reliable source of energy that does not directly emit greenhouse gases or other air pollutants, and that can be scheduled to produce power as needed, depending on water availability.
