Advantages and Perspective of Environmentally Friendly Powers 2012-10-15
In the past, thermal power and coal power played the major role in most countries' power supply system. But in recent decades, environmentally friendly powers are catching up in the proportion. Take France and Japan for an example. The proportion of nuclear power supply now constitutes a remarkable part in these two countries' power supply system. Besides nuclear power, other environmentally friends powers like solar power, tidal power, hydropower and wind energy are attracting increasingly great attention.
Different from traditional power supplies like thermal power, new power supplies don't come at the cost of natural resources. As we know, the generation of thermal power relies heavily on the consumption of coal. As a result, coal resources in the worldwide sphere are declining drastically. Now, quite a number of countries have been aware of the problem of exhaustion of traditional power. Quite the opposite, new environmentally friendly powers offer the human race a sustainable option. Take hydropower for an instance. Smart hydropower station generates electricity as natural river flow pushes the turbine which transforms kinetic energy into electricity. Instead, thermal power plant consumes dozens of thousands of tons of coal to provide electricity for industrial and civilian use.
Besides resource conservation, the exploration of environmentally friendly powers also means less environmental pollution. The benefits of traditional power also come together with pollution of the local ecosphere. For example, thermal power plant burns coal to generate electricity. However, in the process, a large amount of fumes will be discharged into the air and exacerbate the air quality. It is said that power generation makes a considerate contribution to the worsening warm house effect. Instead, new powers like nuclear power and wind energy don't produce any byproduct which is hazardous to the environment. Major nuclear states now have established highly sophisticated system to ensure the operation safety of nuclear power plants in their territories.
Among all these kinds of environmentally friendly powers, nuclear power has reached its maturity as countries like France are attempting to further increase its percentage in national power supply system. In regard to wind energy, its development perspective is also sanguine. At present, countries, which have great potential of wind resource to tap, are installing wind turbines and windmill and trying to make full use of the energy. Similarly, hydropower is witnessing steady development. As the informatization of hydropower further advances, hydropower stations will have a more reliable automatic monitoring and control system.
In all, with the advent of environmentally friendly powers, there will be a major change in the national power system. We will certainly see greater application of these new powers in our life.
