A solar cooker is a device that uses the energy of direct sunlight to heat, cook or pasteurize food or drink. The vast majority of solar cookers currently in use are relatively inexpensive, low-tech devices. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order …
Solar energy can be converted into heat energy in a number of ways. The most common way to convert solar energy into heat energy is through the use of solar thermal collectors. Solar thermal collectors absorb the sun’s energy and convert it into heat energy, which can then be used to heat water, air, or …

Solar energy can be converted into electrical energy using photovoltaic cells, also known as solar cells. Solar cells are made from materials that convert sunlight into electrical energy. When sunlight hits the solar cell, it releases electrons, creating an electric current. This current can then be used to power various electrical devices.
Solar energy is energy that is generated from the sun’s radiation. It is a renewable energy source, as the sun’s energy is constantly replenished. Solar energy can be used for a variety of purposes, including generating electricity, heating water, and heating and cooling buildings. Solar energy can also be used to produce hydrogen to be …
A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed …
A hydroelectric power station is a facility that generates electricity through the use of a turbine and a generator powered by the kinetic energy of flowing water. These power stations are typically located near rivers, lakes, and other sources of water, and they use a dam to channel the water through a turbine, which spins …
Hydrogen is the most abundant element in the universe, making up about 75% of all matter. It is a colorless, odorless, tasteless gas that is highly reactive and combustible. Hydrogen fuel is a type of fuel that uses hydrogen as its primary energy source. This fuel can be used in fuel cells to generate electricity, …
The calorific value of a fuel is the amount of heat energy released when it is burned. It is usually measured in kilojoules per kilogram (kJ/kg) or British thermal units per pound (Btu/lb).
Fuel efficiency is a measure of how much fuel an engine consumes in relation to the amount of work it produces. It is usually expressed in terms of miles per gallon (MPG) for cars and trucks, or gallons per hour (GPH) for aircraft. Fuel efficiency is important because it affects the cost of running a …
Biogas is a renewable energy source derived from the breakdown of organic matter such as food waste, agricultural waste, and sewage. The organic matter is broken down in an anaerobic digestion process which produces a mixture of methane (CH4) and carbon dioxide (CO2). This mixture can be used as a fuel for electricity generation, heating, …
