Установите соответствие заголовков а—н абзацам текста 1 — 5. используйте каждую букву только один раз. в один заголовок лишний. solar energy: the myths? the facts! a current solar devices aren't effective; a breakthrough is needed. в solar energy is too expensive. с more energy is needed to manufacture solar equipment than is saved in its lifetime. d solar energy can only heat water. e to collect enough solar energy requires large areas of collectors. f solar energy can't be used at night. g there isn't enough solar energy to maintain our current lifestyle. h solar doesn't yet supply much energy on global scale. solar and other renewable energy supply options have the capability to supply a large proportion of our energy requirements. the increased use of renewable energy technologies will reduce pollutants and greenhouse-gas emissions as the energy is derived from the natural source of sun, wind, water and biomass. 1 myth: reality: solar (renewable) energy includes the production of electricity and heat directly from solar radiation for many applications. designing your house to use solar energy passively can provide 60% - 100% of your heating and cooking requirements. solar cells, wind generators and hydro can supply electricity for any use. biomass fuels include wood, alcohol, and methane for heating, electricity generation or transportation. 2 myth: reality: solar heat can be stored in thermal mass so it is available on demand at any time. in a solar efficient designed house, the building elements themselves store the energy in their thermal mass for nighttime comfort and for cloudy days. electricity from solar cells can be stored in batteries. 3 myth: reality: there is sufficient roof space on homes alone to produce the total electricity requirements using existing solar technology. wind generators occupy only a small space for the tower with the rest of the land area being available for agricultural uses. solar supply allows the use of small modules which can be accurately matched to the load and which minimize electricity distribution. 4 myth: reality: even ignoring the bias in the statistics, solar (renewable) energy supplies 28% of the world's energy now, made up of 14,4% biomass and 7,5% hydro. in comparison nuclear supplies 4,4%. solar supplies all the energy used to grow plants, to evaporate water for rain and to maintain the temperature of the planet, all necessary for human life. 5 myth: reality: a solar water heater will repay its energy 'debt' in only 6 to 18 months, depending on the location, and will last well in excess of fifteen years. solar cells module will collect over its operating life four times the energy used in its production.
