The solar energy obtained on Earth is the energy of the electromagnetic radiation flowing from the Sun to Earth. We will continue to receive this stream of energy until the nuclear reaction on the Sun runs out of fuel, about 5 billion years from now.
It is possible to directly capture this energy through the photovoltaic effect, converting the photon energy of the Sun into electricity, as in the solar cell. The energy of photons can also be absorbed to heat objects, ie, converted to heat, used in solar water heaters, or boiled in solar thermal power plants, Dynamic heat systems such as the Sun regulator.
The energy of the photons can be absorbed and converted into energy in the chemical bonds of photo-chemical reactions.
A natural photocatalytic reaction is the process of photosynthesis. This process is thought to have previously stored solar energy on non-renewable fossil fuels that industry in the 19th and 21st centuries has been taking advantage of. It is also the process of supplying energy to all natural biological activities, for animal and fuel pulling, and for renewable energy sources. In the future, this process could help generate renewable energy sources in biofuels, such as liquid fuels (biodiesel, fuel from vegetable oil), gas (biogas) .
Solar energy is also absorbed by Earth's hydrosphere and the Earth's atmosphere to generate meteorological phenomena that can be exploited. In this energy model, Earth, like the kettle of the first heat engines, converts the heat absorbed from the sun's photons into the kinetic energy of water, air and air streams. , And change the chemical and physical properties of these flows.
The viability of rainwater can be stored in dams and run on generators of hydroelectric projects. A form of leveraging the flow of rivers and streams before hydropower was born was a water mill. The flow of the sea can also move the generator of the power plant using the flow of the sea.
The flow of air, or wind, can generate electricity when turning wind turbines. Before wind generators were born, windmills were used to grind grain. Wind energy also causes wave motion on the surface. This movement can be utilized in marine power plants.
The Earth's oceans have their own heat capacity greater than air and thus change the temperature more slowly than air when absorbed by the same amount of heat from the Sun. The ocean is hotter than air at night and cooler than air in the daytime. This temperature difference can be exploited to run thermal engines in marine thermal power plants.
As heat absorbed from the photon of the sun evaporates into the sea, some of that energy is stored in the saltwater from the seawater. The freshwater-saltwater power plant collects this energy when it returns the fresh water of the river....bởi Võ Thị Thanh Nga
