1) New renewable (small hydro, modern biomass, wind, solar, geothermal and bio fuels) grow very gradually.
2) Wind power can’t find its application in modern world.
3) Spain has the largest renewable energy program involving production of ethanol fuel from sugar cane.
4) The Earth – Atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation.
5)Most radiation is absorbed at high latitude, and it is dissipated around the globe in the form of winds and ocean currents.
6) Renewable energy is derived from natural processes that are never replenished.


Ex. 5 Make up sentences from two parts:

1) Some renewable energy technologies are criticized… 2) Renewable technologies are also suited to small off – grid applications… 3) Wave motion may play a role in the process of transferring mechanical energy… 4) Solar energy is responsible for the distribution of precipitation and … 5) Renewable energy flows involve natural phenomena such as… between the atmosphere and the ocean through wind stress. for the growth of plants used to create bio- fuels. sunlight, wind, tides and geothermal heat. for being intermittent or unsightly, yet the renewable energy market continues to grow. sometimes in rural and remote areas where energy is often crucial in human development.

Ex. 6 Find the English equivalents of the following words and word combinations:

Возобновляемая энергия Природные ресурсы потребление энергии биотопливо ежегодно солнечные теплоэнергостанции сахарный тростник равновесие распределение осадков поступающая радиация большая часть Equilibrium a major fraction annually solar thermal power station distribution of precipitation renewable energy incoming radiation bio-fuel energy consumption sugar cane natural resources

4) Most radiation (to absorb) at low latitudes around the equator.
5) Renewable energy (to derive) from natural processes that (to replenish) constantly.


Ex. 8 Find Participles in the following sentences and define their forms.

1) Renewable energy is energy generated from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished).
2) New renewables (small hydro, modern biomass, wind, solar, geothermal, and bio-fuels) accounted for 2.4% grow very rapidly.

3) Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18% of the country's automotive fuel.

4) Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.
