THE TRUTH of Low Carbon Emissions When 技術士試験　試験に出る　カーボンニュートラル at the house of the future, the envelope could well contain a nice surprise. Rather than showing just how much the family owes, it may well contain a cheque to cover the power 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 small amounts of electricity on-site, which 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 warm water will be integral to reducing carbon emissions and improving energy security.    To meet 技術士試験　試験に出る　カーボンニュートラル of reducing carbon emissions by 60% by 2050 (based on 1990 levels) takes a radical shift in energy policy, especially as power stations in the UK are responsible for generating over half of them.    This is given sustained 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 be zero carbon - attained by a combination of improved air-tightness and thermal efficiency together with the usage of microgeneration technologies...  This will be utilised by low carbon homes - by 2016 all new build will be zero carbon - achieved by a combination of improved air-tightness and thermal efficiency alongside the usage of microgeneration technologies such as for example 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 planning rules, due autumn 2007, imply that these should be much easier to install. In line with the white paper, only 1 1,300 eco-pioneers have installed panels on the homes while solar water heaters are much more widespread - the Department of Trade and Industry estimates there are about 80,000 used - because they are much cheaper to set up.    Mini wind turbines have also taken off in recent years, with an increase of than 20,000 used by householders or smaller businesses around the UK. They are only viable in some areas where average wind speeds are high enough and there's little wind turbulence from neighbouring buildings.    Ground and air source heat pumps are also set to see a massive growth in demand as on average for each 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. This applies as equally to commercial developments as much as individual homes.    In London, where 75% of the city's carbon emissions result from buildings, the London Climate Change Agency, that 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.
