Ocean Thermal Energy Conversion (OTEC): Energy from the ocean. This uses the temperature difference between solar-heated seawater and cold water at a depth of around 762 meters below the sea surface to produce electricity. OTEC is not affected by wave and tidal changes. As long as the sun shines on the ocean, this fuel is free. Because the solar energy stored in the ocean is inexhaustible.
Essentially, the ocean is the largest collector of solar energy on Earth. It collects around 37,000 billion kilowatts of energy each year, or 4,000 times the electricity consumed by humans worldwide! The energy contained in a typical square kilometer of ocean surface is equivalent to more than 10,000 barrels of oil. Compared to other marine energy sources, the advantages of OTEC are obvious. For example, the kinetic energy of waves and ocean currentsues is weak and fluctuates, and they cannot run the generators consistently and stably.
Renewable energy sources include: solar energy, wind energy, hydroelectric energy, geothermal energy, difference energy ocean temperature, biomass energy, etc.
1. Solar energy
Solar energy is a renewable energy source. It refers to the energy of thermal radiation from the sun and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
2. Wind energy
Wind energy is the kinetic energy generated by air flow. A converted form of solar energy. Due to the uneven heating of various parts of the earth's surface caused by solar radiation, the pressure distribution inthe atmosphere is unbalanced. Under the action of the horizontal pressure gradient, the air moves in the horizontal direction to form wind.
3. Hydropower
Hydraulic power is a renewable energy source and hydropower is mainly used for hydroelectric power generation. Hydroelectricity converts the potential and kinetic energy of water into electrical energy. A plant that produces electricity from water is called a hydroelectric plant, or hydroelectric power station for short, also known as a hydroelectric power station.
4. Geothermal energy
Geothermal energy is natural thermal energy extracted from the earth's crust and exists in the form of heat. for energy from volcanic eruptions and earthquakes.
5. Ocean temperature difference energy
Among the different types of ocean energy, difference energyocean temperature belongs to the thermal energy of the oceans, and its main energy source is the solar radiation energy contained in the ocean. The ocean temperature difference energy has the characteristics of huge reserves and relatively stable changes over time. Therefore, using ocean temperature difference energy to generate electricity is expected to provide stable and large-scale energy in some regions.
6. Biomass Energy
Biomass energy is the energy provided by living plants in nature. These plants use biomass as a means of storing solar energy and are renewable energy sources.
