Sentences with phrase «because solar water heating»

Because solar water heating can reduce the electricity or fuel used to heat water by 50 % or more, the pollution caused by water heating is reduced by the same amount.

Not exact matches

Winston's postdoc Lun Jiang notes that in the 1990s, evacuated tubes used for solar water heating cost more than US$ 100 per meter, but they now cost just $ 2 — 3 because of mass production driven by widespread use of the systems in China.

Because water has good properties as a coolant, antifreeze is used in internal combustion engines and other heat transfer applications, such as HVAC chillers and solar water heaters.

A minimum of 80 % of the electricity purchased for the building is required to come from renewable sources, solar panels are used for heating water in the complex and the building employs a computerised management system which senses the temperature in different parts of the Parliament, and automatically opens windows to keep the building cool especially during the summer when, because of the high level of insulation used to keep the building warm during the winter months, there can be potential problem of overheating.

This is odd because solar — including photovoltaics, concentrating solar thermal, and solar space & water heating — is a mature, commercialized technology that is already being installed in quantity today, both as centralized utility - scale electricity generation and as distributed, small - to - mid-scale electricity and heat generation.

This is also true to a lesser extent with solar thermal, because during long cloudy periods storing the heat in saline water tanks may not be cost effective.

It's because both land and ocean surfaces are heated by shortwave solar radiation and where aerosols reflect SWR equally well over land or water and where greenhouse gases work by retarding the rate of radiative cooling which is not equal over land and water.

The concentrated solar thermochemical process provides the most promising technology for splitting water and carbon - dioxide molecules, scientists say, because of its direct conversion of high - temperature solar process heat into chemical energy.

Note, for example, how the temperature trend in the first decade of the 21st century was generally flat because an upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures continued to rise).»

For example, the scientific explanation that temperatures have not risen since 2001 is because an «upward push by anthropogenic forces was temporarily offset by a downward pull as solar activity decreased and the oceans absorbed more heat than usual from the atmosphere (sea water temperatures continued to rise)».

Because most heating systems burn fossil fuels, which creates pollution, all the energy saved by a solar water heating eliminates the pollution that would otherwise add to our problems of poor air quality, poor health, smog and global climate change, a problem which requires immediate action.

Because solar heating has declined and (according to the IPCC) added CO2 has little impact on heating tropical waters as discussed in part 2, subsurface heat should decline and future ventilations will not cause a resumption in a warming trend.

Because most solar systems only send solar hot water to the backup heater when you are using hot water, the sun can only heat the remaining two - thirds of the energy used each day.

Eventually the latent heat plateu is breached because real - time solar power has the ability to do that, and heats the water to still higher temperature.

Eventually the latent heat plateu is breached because real - time solar power has the ability to do that, and heat the water to still higher temperature.

But, because it is much cheaper to heat water with the sun than to produce electricity from the sun to heat water, a secondary system to provide solar hot water was planned.

Indeed in our universe water could never exist in liquid form because solar energy would always heat the molecules and their surroundings to above the point at which they could exist in liquid form.

That's unfortunate, according to scientists at the Dr Panjabrao Deshmukh Agricultural University in India, because using the sun's power to heat water is a far more efficient process and offers a much quicker return on investment: According to their analysis, published in the International Journal of Global Energy, as the payback time for a solar water heating system is about two years (with a lifespan of 20), this is a far more cost - effective use of solar energy in the developing world than using it to generate electricity.
