Air Source Heat Pump Description and Operation: A heat pump is classified according to the source from which it extracts heat‚ i.e. the low temperature heat source. One that collects and utilises thermal energy from the outside air to heat the home and provide domestic hot water is called an air source heat pump. In an air source heat pump‚ outdoor air is drawn into the heat exchanger‚ which contains coils filled with a pressurised refrigerant gas. The refrigerant gas referred to here is

Oil prices have risen to an ultimate level; congress must look into the still tiny alternative energy market. In a minimum of fifty years fossil fuels‚ which include petroleum (oil)‚ natural gas‚ and coal‚ will all run out. Alternative energy is a renewable and the most productive type of energy for the USA and the world (United States. Department of Energy). Every person on this planet is provided with a dirty and unforgiving energy source‚ fossil fuels. Fossil fuels destroy and tarnish the once

Calories: The name calorie is used for two units of energy. Although these units are part of the metric system‚ they have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. Calories are also most known to be used in foods and diet‚ which is key to athletes. Joules: A Joule is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. Kilocalories:

------------------------------------------------- Are There Any Realistic Alternatives To Oil? While energy cannot be created or destroyed‚ it can be transformed between types. The main sources of energy on Earth are the fossil fuels‚ including coal‚ natural gas‚ and oil‚ and all of these are nonrenewable resources. Each of these were produced over a period of millions of years under the surface of the Earth‚ and it is not possible to renew these supplies. The main uses for the energy obtained from the fossil fuels include heating

Warming and Alternative Energy People are inflicting major damage to the Earth’s environment‚ and if we don’t do anything to stop the destruction soon‚ the results could be devastating. Most people know about global warming and think it may be a serious problem in the future. What most people don’t understand is that global warming is happening now‚ and we are already feeling some of its destructive power. Because of the dangerous effects of global warming‚ alternative energy sources need to be
