The Ocean, Nuclear and Solar Power are forms of alternative energy which can be urban.
Ocean Thermal Energy Conversion (OTEC) is a potential alternative energy source that needs to be funded and explored much more than it presently is.
There are three kinds; closed, open and fusion cycle of OTEC.
“Closed Cycle” uses a low-boiling point liquid such as, for example, propane to act as an intermediate fluid. The OTEC plant pumps the warm sea water into the reaction chamber and boils the intermediate fluid. This results in the intermediate fluid’s vapor pushing the turbine of the engine, which thus generates electricity. The vapor is then cooled down by putting in cold sea water.
“Open Cycle”. The sea water itself is the driver of the turbine engine in this OTEC format. Warm sea water found on the surface of the ocean is turned into a low-pressure vapor under the constraint of a vacuum. The low-pressure vapor is released in a focused area and it has the power to drive the turbine. To cool down the vapor and make desalinated water for human consumption, the deeper ocean’s cold waters are added to the vapor after it has generated sufficient electricity.
“Fusion Cycle” There are really two sub-theories to the theory of Fusion Cycling. The first involves using a closed cycling to generate electricity. This electricity is in turn used to make the vacuum environment needed for open cycling. The second component is the integration of two open cyclings such that twice the amount of desalinated, filtered water is produced that with just one open cycle.
Developing Nuclear Power as Alternative Energy
Nuclear power plants are very “clean-burning” and their efficiency is rather staggering. Nuclear power is generated at 80% efficiency, meaning that the energy produced by the fission reactions is nearly copy to the energy place into producing the fission reactions in the first place. There is not a lot of waste material generated by nuclear fission—even if, due to the fact that there is no such thing as making energy without also making some measure of waste, there is some. The concerns of people such as environmentalists with regards to using nuclear power as an alternative energy source center around this waste, which is radioactive gases which have to be contained.
Solar Energy Collecting as an Alternative Energy Source
Solar powered electricity generation is certainly excellent for the environment, as this alternative form of producing energy gives off unquestionably zero emissions into the atmosphere and is merely utilizing one of the most genuinely occurring of all things as its driver. Solar collection cells are becoming at a snail’s pace but surely ever more practical for placing upon the rooftops of people’s homes, and they are not a hard system to use for heating one’s home, making hot water, or producing electricity. In the case of using the photovoltaic cells for hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through your pipes.
