THE TRUTH of Low Carbon Emissions When the electricity bill lands at the house of the future, the envelope may contain a nice surprise. Rather than showing just how 技術士二次試験　必須問題　カーボンニュートラル owes, this could contain a cheque to cover the energy it has generated for the national grid!    The government's recently published energy and planning white papers combine to sketch a rosy future for householders generating smaller amounts of electricity on-site, that is then used to power a home's Lighting, Heating and electrical appliances. Any excess power generated can be exported back to the grid.    The energy white paper 'Meeting the Energy Challenge' ushers in a potentially bright future for electricity with detailed proposals pointing to how electric heating and hot water will be integral to reducing carbon emissions and improving energy security.    To meet the government's target of reducing carbon emissions by 60% by 2050 (predicated on 1990 levels) takes a radical shift in energy policy, especially as power stations in the united kingdom have the effect of generating over 1 / 2 of them.    This is given even greater emphasis by the truth that by 2020, 80% of the UK's gas requirements should be imported and over half the world's gas reserves are concentrated in just three countries, Russia, Iran and Qatar.    The white paper pushes for investment in increasingly low carbon electricity, principally large-scale renewables, clean coal and nuclear power.    Illustration of a 'greener' home    Microgeneration    ...by 2016 new build will undoubtedly be zero carbon - attained by a combination of improved air-tightness and thermal efficiency together with the use of microgeneration technologies...  技術士二次試験　必須問題　カーボンニュートラル is utilised by low carbon homes - by 2016 new build will undoubtedly be zero carbon - attained by a variety of improved air-tightness and thermal efficiency together with the usage of microgeneration technologies such as solar panels, wind generators, biomass boilers and heat pumps in addition to heat recovery ventilation systems.    Solar panels or photovoltaic cells are accustomed to generate power from sunlight and changes to the look rules, due autumn 2007, imply that these should be much easier to install. According to the white paper, only 1 1,300 eco-pioneers have installed panels on their homes while solar water heaters are a lot more widespread - the Department of Trade and Industry estimates you can find about 80,000 in use - as they are much cheaper to install.    Mini wind turbines have also taken off in recent years, with an increase of than 20,000 in use by householders or smaller businesses around the UK. They are only viable in a few areas where average wind speeds are high enough and there is little wind turbulence from neighbouring buildings.    Ground and air source heat pumps may also be set to visit a massive growth popular as on average for each and every 1 kW of electricity they consume they produce around 2 to 3 3 kW of heat.    Generating electricity locally avoids transmission losses and enables waste heat to be exploited for both heating and cooling. 技術士試験　試験に出る　カーボンニュートラル applies as equally to commercial developments around individual homes.    In London, where 75% of the city's carbon emissions come from buildings, the London Climate Change Agency, which is championed by god, the father Mayor's office, is encouraging the growth of mixed-use developments which lend themselves to CHP (combined heat and power) systems, with residential and commercial property providing a balanced demand for energy around the clock.
