What are the types of new energy power generation? What is new energy power generation and what form

Compared with the widely used conventional energy sources (such as coal, oil, natural gas, hydropower, etc.), new energy refers to unconventional energy sources developed and utilized on the basis of new technologies, including wind energy, solar energy, marine energy, geothermal energy, biomass energy, hydrogen energy, nuclear fusion energy, natural gas hydrate energy, etc. New energy power generation refers to the process of converting new energy into electrical energy. Wind power generation and solar power generation, as a new energy power generation mode with mature technology, large-scale development and commercial application, the development speed is in the forefront of new energy, and its main characteristics are:

Renewable, widely distributed, low pollution; Low energy density and small single machine capacity; intermittent, periodic, random, volatile; Extensive adoption of power electronics; There are two typical ways to access the power grid: decentralized and centralized development. Explanation of terms: Renewable energy:

Energy that can be continuously regenerated in nature and regularly replenished or reused. For example, non-fossil energy sources such as solar, wind, hydro, biomass, and tidal energy.

Clean energy: renewable energy that produces no or few pollutants after consumption, fossil energy with low pollution (such as natural gas), and fossil energy (such as clean coal and clean oil) that is treated with clean energy technologies. Generally speaking, conventional energy refers to energy that is technically mature and has been used on a large scale, while new energy usually refers to energy that has not been used on a large scale and is being actively researched and developed.

Therefore, coal, oil, natural gas, and large and medium-sized hydropower are all regarded as conventional energy sources, while solar energy, wind energy, modern biomass energy, geothermal energy, marine energy, and hydrogen energy are regarded as new energy sources. With the progress of technology and the establishment of the concept of sustainable development, the industrial and domestic organic waste, which has been regarded as garbage in the past, has been re-recognized, and has been deeply researched and developed as a material for energy resource utilization, so the resource utilization of waste can also be regarded as a form of new energy technology. The energy resources that have recently been developed and utilized by human beings and need to be further researched and developed are called new energy, and compared with conventional energy, new energy has different contents in different historical periods and scientific and technological levels.

There are solar, wind, hydro, etc.

1. Hydroelectric power plants.

The essence of a hydroelectric power plant is that a waterwheel drives a generator to convert energy, and designers usually use earth, rock or concrete to lay it outside, which is often suitable for flood control or to resist water impact. Model designers often use waterwheels for calculations, as this is the essence of hydropower.

2. Thermal power plants.

Thermal power plants, abbreviated as thermal power plants, are factories that use combustibles, such as coal, as fuel to produce electricity. Its basic production process is that the fuel heats water to produce steam when burned, and the chemical energy of the fuel is converted.

Converted into thermal energy, the steam pressure pushes the steam turbine to rotate, and the thermal energy is converted into mechanical energy.

The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy.

3. Wind power plants.

Wind power plants, referred to as wind power plants, are power plants that use wind to generate electricity, and are renewable energy.

A type of power plant. Currently, due to the Kyoto Protocol of the United Nations.

Reducing greenhouse gas emissions.

In this case, wind power plants have become the preferred energy development priorities of all countries.

4. Tidal power plants.

Tidal power is a form of hydroelectric power that uses the movement of tidal currents, or the rise and fall of tidal seas, to obtain energy from them. Although not yet widely used, tidal power has great potential for the future of electricity**. In addition, it is easier than wind and solar**, and in Europe the tides have been used to drive mills for thousands of years, mainly for grinding grains.

5. Nuclear power plants.

A nuclear power plant is the use of a nuclear reactor.

The thermal energy generated by the fission chain reaction of nuclear fuel is converted into mechanical energy and then converted into electrical energy according to the power generation method of thermal power plants, and its nuclear reactor is equivalent to the boiler of thermal power plant.

Development status. Since the 20th century, the demand for electricity has increased almost every 10 years.

By the mid-90s of the 20th century, the main forms of power generation were hydropower, thermal power and nuclear power. The United States, Russia, the United Kingdom, Italy, China and other countries are dominated by thermal power generation, accounting for more than 70% of their power generation.

Japan and Germany account for more than 60% of thermal power. Norway, Switzerland, Brazil all account for about 90% of the total hydropower generation, Canada more than 60%, Sweden.

It is also more than 60%. Finland and Yugoslavia.

then hydropower and thermal power each account for 1 2. France is dominated by nuclear power, which generates more than 70% of the total electricity generation.

Between 1980 and 1986, the proportion of thermal power decreased year by year, the proportion of hydropower decreased, and the proportion of nuclear power increased.

Nuclear fusion, solar thermal, coal, oil and gas combustion power generation, geothermal, waste heat power generation, nuclear fission.

New energy (NE): also known as unconventional energy. It refers to various forms of energy in addition to traditional energy sources. It refers to the energy resources that have just begun to be developed and utilized or are being actively researched and to be promoted, such as solar energy, geothermal energy, wind energy, marine energy, biomass energy and nuclear fusion energy.

In 1981, the United Nations convened the "United Nations Conference on New and Renewable Energy" to define new energy as: based on new technologies and new materials, the traditional renewable energy has been modernized and utilized, and it is inexhaustible.

Renewable energy sources are being used to replace fossil fuels with limited resources and polluting the environment, focusing on the development of solar, wind, biomass, tidal, geothermal, hydrogen and nuclear (nuclear).

The types of new energy include: hybrid electric vehicles, pure electric vehicles, fuel cell vehicles, hydrogen-powered vehicles, gas vehicles, and flywheel energy storage vehicles.

1. Hybrid electric vehicles.

Hybrids refer to vehicles that run on conventional fuels and are equipped with electric motors and engines to improve low-speed power output and fuel consumption. Depending on the type of fuel, it can be divided into gasoline hybrid and diesel hybrid.

2. Pure electric vehicles.

As the name suggests, BEVs are primarily powered by electricity. Most vehicles are directly driven by electric motors, some mounted in the engine compartment, and some directly use the wheels as the rotors of the four electric motors. The challenge lies in energy storage technology.

3. Fuel cell vehicles.

Fuel cell vehicles are vehicles that use hydrogen, methanol, etc. As fuel, an electric current is generated through a chemical reaction and is driven by a motor. The energy of the battery is converted directly into electricity through the chemical action of hydrogen and oxygen, rather than through combustion.

The chemical reaction process of fuel cells does not produce harmful products, so fuel cell vehicles are pollution-free vehicles.

4. Hydrogen-powered vehicles.

Hydrogen-powered vehicles are truly zero-emission vehicles that emit pure water. It has the advantages of no pollution, zero emission, and abundant reserves. Therefore, hydrogen-powered vehicles are the most ideal alternative to conventional vehicles.

5. Gas vehicles.

The gas has a single composition, high purity, uniform mixing with air, complete combustion, low carbon monoxide and particulate emissions, and good engine low temperature start and running performance. Its disadvantages are worse transport performance than liquid fuel, low engine volume efficiency, long ignition delay time, and reduced power performance.

6. Flywheel energy storage vehicle.

The inertial energy storage of the flywheel is used to store the remaining energy when the engine is not fully loaded and the energy when the vehicle grows and decelerates downhill, and feeds back to the generator to generate electricity, which drives or accelerates the flywheel to rotate. As an auxiliary in hybrid electric vehicles, it has the advantages of improved energy utilization efficiency, light weight, high energy storage, fast response to energy in and out, and maintenance.
