Renewable energy Statistics 2023

Renewable energy Statistics 2023

Renewable energy refers to energy sources that are replenished naturally on a human timescale, such as solar, wind, hydroelectric, and geothermal power. These energy sources are considered renewable because they are not depleted when used, unlike nonrenewable sources such as fossil fuels (e.g. coal, oil, and natural gas), which are finite and will eventually be exhausted.

There are many different statistics that can be used to measure the use and effectiveness of renewable energy. Some common statistics include:

  • Renewable energy capacity: This measures the total amount of renewable energy that is available to generate electricity. It is typically measured in megawatts (MW) or gigawatts (GW).
  • Renewable energy generation: This measures the amount of electricity that is actually generated from renewable energy sources. It is typically measured in kilowatt-hours (kWh) or terawatt-hours (TWh).
  • Renewable energy share: This measures the percentage of total energy consumption that is supplied by renewable energy sources. It is typically expressed as a percentage.
  • Renewable energy cost: This measures the cost of generating electricity from renewable energy sources, compared to nonrenewable sources. It is typically measured in dollars per kilowatt-hour (kWh).
  • Renewable energy jobs: This measures the number of jobs that are related to the renewable energy industry, including manufacturing, installation, maintenance, and research and development.

There are many different organizations that track and publish renewable energy statistics, including the International Energy Agency, the Renewable Energy Policy Network for the 21st Century, and the U.S. Energy Information Administration.

What is Hydrogen energy and how does it work?

What is Hydrogen energy and how does it work?

Hydrogen energy is a form of energy that is stored in the chemical bonds of hydrogen atoms. It can be used to power a variety of devices, including fuel cells, internal combustion engines, and even small electronic devices like laptops and cellphones.

One of the most common methods is through the electrolysis of water, in which electricity is used to split water molecules into hydrogen and oxygen. The hydrogen can then be stored in tanks or fuel cells and used as a fuel source.

Hydrogen can be used to power fuel cells, which are devices that use a chemical reaction between hydrogen and oxygen to produce electricity. In a fuel cell, hydrogen and oxygen are combined in a chamber to produce electricity, heat, and water. The electricity produced can be used to power a variety of devices, including cars, homes, and businesses.

Another way hydrogen can be used for energy is by burning it in internal combustion engines. These engines are similar to the ones found in gasoline-powered cars, but instead of using gasoline, they use hydrogen as a fuel. When burned, hydrogen reacts with oxygen in the air to produce water and heat, which can be used to power the engine.

Overall, hydrogen energy is a clean and efficient source of energy that has the potential to play a significant role in the transition to a low-carbon economy.

Being a renewable energy

Pros and cons of geothermal energy

Pros of geothermal energy : 

Being a renewable energy, it is one of the sources of energy that does not run out at least for future generations.
Being a clean energy that is not harmful to the environment, and does not cause any pollution either in its extraction, conversion or use.
It is available in very large quantities, in vast areas and for most countries of the world.
Low energy production costs after the initial costs of Station production (which can be prohibitive).
High yield of extracted energy.

cons of geothermal energy : He covered all the advantages of geothermal energy, which made it at the forefront of future alternative energy sources. However, there are some factors that are difficult to spread, at least for the time being. One of the most important of these reasons is the high cost of erecting power plants using geothermal energy. This is due to the difficulty of drilling wells at great depths and amid very high temperatures.
Although geothermal energy is less expensive than any other energy source, it is exhaustible and can create environmental problems . When it is exhausted in one facility, it leads to the loss of the entire facility. Some facilities also emit large amounts of sulfur, which can be equivalent to what is released by similar-sized facilities using coal fuel with a high sulfur content. Although geothermal applications will expand in the future, they are not expected to cover more than 5-10% of global energy needs, mainly due to the lack of convective water systems in many parts of the world.

 

Types of geothermal power plants

Types of geothermal power plants

Power plants operating by dry steam method : It is the most widespread type, and it works by pumping hot steam directly from the hot water reserves located in the ground to the turbine, which rotates the electric generator connected to it and thus generates electrical energy. After the hot steam passes through and circulates to the turbine, the Steam is condensed and thus converted into water, which is returned to the underground via an injection well.

Fumigation power plants : These stations differ from dry steam stations in that instead of steam, hot water is pumped at high pressure directly to the evaporation tank located on the surface of the Earth. The temperature of the evaporation tank is low, as well as its pressure is low, and this decrease in heat and the difference in pressure causes the evaporation of hot water, steam is formed, which is directed towards the turbine to rotate and the electric generator rotates with it. After that, the Steam is cooled and condensed to become water, which is returned to the ground via an injection well.

Dual-circuit power plants : Dual-circuit power plants differ from the previous ones in that steam from underground water does not reach directly to the turbine, but hot water is pumped from underground to a heat exchanger where hot water passes through pipes in a different liquid with a low boiling point (below the boiling temperature of water). The second liquid is converted into steam by the heat of the water in the pipes, and it goes to the turbine, which rotates and the electric generator rotates with it. After that, the water returns to the underground by the injection well, while the steam that rotated the turbine is condensed and returns to the heat exchanger to be used again.

Geothermal energy

Geothermal energy

Geothermal energy It is a high thermal energy of natural origin stored in magmIt is estimated that more than 98% of the Earth’s mass is made up of rocks whose temperature exceeds 1000 degrees Celsius. The temperature rises as we go deeper into the Earth at a rate of about 2.7 degrees Celsius per 100 meters in depth, and this thermal energy is mainly used to generate electricity, and this requires drilling many pipes to depths of up to about 6 kilometers. Sometimes hot water is used for heating when the heat is close to the surface of the Earth, and we find it at a depth of 160 meters or sometimes in certain areas in the form of hot springs that reach the surface of the Earth.a in the Earth’s interior.This renewable energy can be enough to cover the world’s energy needs for the next 10,000 years, but converting it into electrical energy is an expensive process due to drilling operations to great depths and the need for many pipes to extract hot water in large quantities, although thermal energy is free and is widely available but difficult to obtain.The geothermal energy rate is estimated to be about twice as much as all the energy used by modern man from various sources. In addition to the energy coming from the geological depths of the Earth, the Earth’s surface receives the sun’s energy and stores it in the surface layer, estimated to be 10 meters thick during the summer months and releases it during the winter months.

Cons of wind power

Despite the many advantages of wind, there are some disadvantages or challenges that can arise when relying on wind energy, such as:
– Unreliable source : in general, it is not possible to be sure of the wind blowing reliably, therefore, if it relies on wind only to generate electricity, which leads to a lack of electricity on days when the wind does not blow, and on the other hand, severe storms, high winds or lightning damage wind turbines.
– Threat to wildlife : turbines and their feathers and edges can be unsafe for wildlife, especially for birds that are in the same area, and there is no effective and reliable way to prevent such a threat.
– Noise and visual pollution : wind turbines emit a sound ranging from 50 to 60 decibels, therefore, if the turbine is next to the house, it will make an annoying noise, and on the other hand, some consider that The Shape of turbines, especially next to houses, is ugly and gives an unloved appearance to the place.
– Cost and maintenance : although wind energy is lower in cost than other energy sources, it remains expensive when starting a turbine construction project, and its maintenance is expensive.
– Safety: turbines can threaten the safety of workers in the field, especially during times of severe storms and high winds, which cause damage or problems in the turbine blades, increasing the likelihood of their occurrence, which threatens the safety of workers, causing them lifelong disability or causing their death.
– Limitation : the harnessing of wind energy is limited to certain places only, which are places where the wind speed is high, and this is mostly in remote places away from cities.
