Mechanical Systems of Engineering

Wind energy is a form of natural resource of energy and renewable, inexhaustible and pollutant free source and available abundant in the nature. Wind energy can be converted into useful energy such as electricity, mechanical energy i.e. pumping of water etc.

BIOPOWER: ENERGY FOR HEAT AND ELECTRICITY

Biopower technologies convert renewable biomass fuels into heat and electricity using processes like those used with fossil fuels. There are three ways to harvest the energy stored in biomass to produce biopower: burning, bacterial decay, and conversion to a gas or liquid fuel. Biopower can offset the need for carbon fuels burned in power plants, thus lowering the carbon intensity of electricity generation. Unlike some forms of intermittent renewable energy, biopower can increase the flexibility of electricity generation and enhance the reliability of the electric grid.

Tidal energy is a form of hydro power which converts the energy obtained from tides into other useful energies (electricity). The tidal energy is the result of the sun and moon's influence over the ocean. The height difference between low and high tides gives rise to tidal currents in coastal areas, which drives the turbines.

Tidal energy is also called tidal power. Tidal power utilizes the energy contained in tides to produce electricity.

Geothermal Energy is a “carbon-free, renewable, sustainable form of energy that provides a continuous, uninterrupted supply of heat that can be used to heat homes and office buildings and to generate electricity.” Geothermal energy is the heat that comes from the sub-surface of the earth. It is contained in the rocks and fluids beneath the earth’s crust and can be found as far down to the earth’s hot molten rock, magma.

To produce power from geothermal energy, wells are dug a mile deep into underground reservoirs to access the steam and hot water there, which can then be used to drive turbines connected to electricity generators

A fuel cell is a device that generates electrical energy from chemical reactions. As such, a Proton Exchange Membrane (PEM) fuel cell generates electricity through a chemical reaction between hydrogen and oxygen. The fuel cell requires a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction. Through this reaction fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. This electrochemical process means that the fuel cells operates without pollution with the only by-products being water and heat. This makes fuel cells an ideal part of the transmission to a zero-emission society.
