Approaches to Increase the Use of Renewable Energy

Renewable energy is a sustainable alternative to using fossil fuels, and it provides reliable and diversified energy supplies for fuels, helping to conserve the nation's natural resources, enhance energy security, reduce fuel spill risks, and reduce the need for imported fuels.

Renewable Energy: An Overview

Renewable energy often referred to as clean energy, comes from natural sources such as water, the sun, wind, earth's warmth, and biomass.

Renewable energy provides reliable and diversified energy supplies for fuels, helping to conserve the nation's natural resources, enhance energy security, reduce fuel spill risks, and reduce the need for imported fuels.


The spread of these energy sources increased at the beginning of the twenty-first century, as renewable energy sources covered nearly 20% of global energy use in this century.

16% of the total electric energy in the world was generated through hydroelectric power stations, and other renewable energy sources contributed approximately 6% of the total amount of electricity consumed in this century.

In 2015, 10.6% of electrical energy was generated by nuclear energy, which some consider renewable energy sources.


Increasing the use of renewable energy will allow us to replace carbon-intensive energy sources and significantly reduce global warming emissions. And the increased reliance on renewable energy can help protect consumers when fossil fuel prices rise.

Market-based approaches to using renewable energy are increasingly being preferred as an alternative to "command and control" legislation.


There are many advantages to the use of renewable energy, one of the most important characteristics of renewable energy is that it will allow living in a world free from climate disasters, but this matter requires a lot of time and effort in developing renewable energy sources.


The cost of renewable energy sources has decreased so much that they are less expensive than fossil fuel and nuclear energy. This led to a marked difference in the global economy. Also, it has become possible for many people to generate energy on the roofs of their homes through solar panels.

And one of the most important advantages of renewable energy sources is that they work to reduce global warming, as they affect the environment in a positive way.


Renewable sources do not emit pollutants that cause human and environmental damage around the world, and because non-renewable energy sources will inevitably be implemented, it is imperative that humans move to renewable energy sources quickly before consuming other sources.


Renewable Energy Sources

Renewable energy sources provide enough energy to meet the human needs to be used in various fields, as renewable resources offer an attractive option to provide this necessary energy.

 Renewable energy uses are numerous, as these resources produce clean and environmentally friendly energy. However, renewable energy remains less reliable than non-renewable energy due to the smaller amount produced daily.

 The main sources of renewable energy may include the following:


Biomass: It is the organic materials present and produced from plants and animals. Biomass is considered a source of energy because it absorbs solar energy that can be converted into thermal energy when these organic materials are burned.


Hydropower: Hydroelectric energy has been used for thousands of years, and it is one of the oldest sources of renewable energy. Electricity is generated by mechanical energy resulting from the flow of water. 

Hydropower plants usually use rivers and streams to operate turbines that generate electricity.

 

Geothermal energy: the heat generated in the ground is the source of this energy, and this energy is used by drilling wells capable of pumping water or steam to power plants. These wells are drilled near volcanoes or tectonic plate boundaries because there is a large stock of this energy near them.


Wind energy: This energy is converted into electricity by moving the air or wind to the arms of the turbines, and then the generator converts this energy from mechanical energy into electrical energy, to be used later in homes.


Solar energy: Photovoltaic cells convert solar energy into electrical energy, and these cells generate a small amount of electricity, but when using large solar panels or sheets, they produce a large amount of energy.


Uses of renewable energy

Humans began using renewable energy sources thousands of years ago, and technological development has created innovative ways to harness renewable resources and convert them into electricity.

The uses of renewable energy are many and varied, including homes, companies, and various sectors.

 Among the most important uses of renewable energy are:

 

Household and Commercial Cleaning: renewable energy is of great importance in the lives of residents, and among its most important household uses:

  • Heat water for use in cleaning, bathing, and washing purposes, by using solar collectors, without converting it into any other form of energy, and it is the cheapest form of energy altogether.
  • Heating water with solar energy by using a solar absorber.


The agricultural sector: there are many uses of renewable energy in agricultural use. The electricity generated by solar PV can be used to power agricultural machinery, lighting, and pumping water in the agricultural production process and drying agricultural products.

Solar electricity generation can be in the form of hybrid, off-grid, and on-grid.


The industrial sector: Renewable energy can be used widely in industrial applications including:

  • Distillation and desalination.
  • Charging batteries in TV and wireless stations.
  • The lighting of shipping lanes.
  • Navigation alarms.
  • The operating system of the speakers.
  • Charging electric batteries.
  • Generating electricity in remote villages.


The military sector:  Among the most important applications of renewable energy in the military field, which can be used to facilitate life in the new military cities, are the following:

  • Solar heating system for military colleges, in order to meet students' needs.
  • Supplying units with hot water, by using field solar heaters.
  • Water desalination.
  • Feeding of fixed wireless stations.


The Future of Renewable Energy

Renewable energy has many advantages that are an important indicator of its position in the future, as its sources are diverse and cover the world's energy needs, and even the technologies used to produce it are low in cost and high in efficiency.

The negative health effects are almost non-existent, and renewable energy technologies can be used in homes and businesses and produce their own energy.

There is a strong reception of renewable energy from the people and the desire to use it, and many governments have decisions that support the use of renewable energy. 

Using renewable energy electric motors to power natural gas compressor stations can be an effective way to increase renewable integration.

Using renewable energy in a conservative and effective manner, and not being overused or wasted is the most economical way to conserve energy, such as switching off lights and electrical appliances when not in use. This will save money spent on energy and reduce the environmental impact associated with electricity production.
