THE WIND, SUN AND TIDES are all excellent sources of clean and renewable energy, but you have to take what you can get when the sun is shining, the wind is blowing and the waves are rolling.
The crust of the earth is made up of big plates. Geothermal areas are commonly positioned around the boundaries of crustal plates where geological processes enable magma to rise up to the surface. These regions are frequently connected with volcano activities and earthquakes. As Hong Kong is not situated in these regions, geothermal power is not obtainable right here.
Simply put, the process of extracting power from the earth is incredibly standard. Water is pumped through pipes to the source of this heat, then boiled and the resulting steam runs a turbine that creates electricity. The water then recondensed is sent back via the pipes to repeat the cycle. If the pipes utilized have been sturdy and deep enough, we could push them down to the earth’s mantle resulting in an inexhaustible supply of electrical energy.
In all three of these partnership scenarios, a geothermal unit has two major positive aspects. Initially, the renewable energy aspect permits the utility or third party to use Small business Investment Tax Credits and other federal incentives, further driving down the expense of installation. Second, since the technologies is additional energy-efficient, finish users can expect a considerably reduced utility bill.
According to the United States Department of Power (DOE), the nation’s buildings account for 43 % of U.S. carbon emissions and 39 percent of principal energy consumption. Examine those numbers with the transportation business, which comes in a distant second at 32 % and 28 percent, respectively. What’s more is that the DOE reports 40 percent of the total energy applied in these buildings is for air-conditioning and heat, as nicely as hot water heating.…
