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, …
Biomass is organic material that is derived from plants and animals and is used as a source of energy. It is often burned to produce heat, electricity, or biofuels like biodiesel. Common biomass materials include wood, agricultural waste, and methane from landfills.
Store propane tanks outdoors in a well-ventilated area away from windows, doors and vents. Always turn off the gas at the tank when not in use. Never store extra fuel tanks inside your home. Refill propane tanks only at approved filling stations. Never smoke while handling propane tanks. Keep propane tanks away from heat sources …
CNG (Compressed Natural Gas), LPG (Liquified Petroleum Gas), and LNG (Liquified Natural Gas) are all types of fuels used for transportation and cooking. CNG is derived from natural gas, while LPG is derived from petroleum and LNG is derived from natural gas. All three types of fuel are stored in a compressed, liquefied form for …
Coal is a fossil fuel that is formed from the remains of ancient plants and animals that have been buried and exposed to extreme heat and pressure over millions of years. It is a black or brownish-black sedimentary rock composed primarily of carbon and hydrocarbons. Coal is used as an energy source, primarily to generate …
Fossil fuels are hydrocarbon-containing materials that were formed from the remains of ancient plants and animals. They are found in the Earth’s crust and are a source of energy for many human activities. Fossil fuels include coal, oil, and natural gas, and are used to produce electricity, fuel cars, and heat buildings. Burning fossil fuels …
Combustion of fuel is the chemical process in which fuel reacts with oxygen in the presence of heat to produce energy in the form of light and heat. The process is also known as burning. Common fuels used in combustion reactions include coal, natural gas, oil, and wood.
Light pollution is the excessive use of artificial light that interferes with natural cycles and patterns of light and dark. It is caused by the overuse of energy-inefficient lighting, such as streetlights and security lights, that scatter light into the night sky, making it difficult to see stars and other forms of natural light. Light …
The Tyndall effect is a phenomenon in which light scatters when passing through a colloidal solution. This scattering causes the solution to appear cloudy or hazy, and the color of the solution is dependent on the size of the particles and the wavelength of the light. The Tyndall effect is named after the British physicist …
