Energy is the ability to do work, change, or produce. It
comes in multiple forms such as chemical, nuclear, thermal, kinetic, or
potential energy. It is essential for all natural processes and plays a
significant role in powering the world. The world demand for energy is
continuously increasing as living standards and the world population are
increasing.

RENEWABLE OR NATURE ENERGY

These are the sources that are replaced naturally so that they never run out. They are naturally obtained. They are

• • Biofuels: Include wood, biogas, and bioethanol, it is the main source of energy in rural areas where there are fewer options for electricity available. Since these are produced from various sources including agricultural residues, algae, and non-food crops these provide flexibility in production methods and dependency on other resources.

• • Geothermal: Makes use of the heat from the earth’s core. In Iceland as well as many other volcanic areas there are many hot springs and pools of hot water underground A hole is bored underground where a pipe is installed which reaches the hot rocks, the steam is forced upwards through the pipe and this steam is used to turn a turbine and generate kinetic energy which is transformed into mechanical energy through a generator.  This source is beneficial as it produces carbon dioxide and is renewable as the earth’s core is continuously heating up but it is only limited to certain areas and can encourage seismic activities.

• • Hydroelectric: Uses energy from fast-running water to drive turbines that work the generator and produce electricity. It is the cheapest method of energy production and uses the natural flow of water however building dams is costly and can force people out of living in that area.

• • Solar: Absorbs sunlight to generate heat and uses photovoltaic cells. Solar power is much more expensive than other sources but once running can produce a lot of electricity. Wind: Harnesses electricity from the flowing wind. Although the cost of setting up wind turbines is high, it can generate a lot of energy and is much cheaper than other sources.

Benefits of renewable energy Use

Renewable energy offers a wide range of benefits, contributing to environmental, economic, and social sustainability. Here are some key advantages of renewable energy:

Reduced Greenhouse Gas Emissions: The most significant environmental benefit of renewable energy is its ability to significantly reduce greenhouse gas emissions. Unlike fossil fuels, which release carbon dioxide and other pollutants when burned, renewable sources such as solar, wind, and hydropower produce clean energy without emitting harmful pollutants.

Climate Change Mitigation: By replacing traditional energy sources with renewables, we can mitigate the impacts of climate change. The reduction in greenhouse gas emissions helps to limit global temperature increases, decrease the frequency of extreme weather events, and protect ecosystems.

Energy Security: Renewable energy sources are abundant and distributed globally, reducing dependence on finite and geopolitically sensitive fossil fuel reserves. This diversification of energy sources enhances energy security and reduces the vulnerability of countries to supply disruptions or price fluctuations in the fossil fuel market.

Job Creation: The renewable energy sector has the potential to generate a significant number of jobs. Jobs are created in manufacturing, installation, operation, and maintenance of renewable energy systems, fostering economic growth and employment opportunities.

Cost Competitiveness: The cost of renewable energy technologies, particularly solar and wind, has been decreasing steadily. As a result, renewables are becoming increasingly competitive with traditional energy sources. This cost reduction makes renewable energy more accessible and economically viable.

Resource Sustainability: Unlike fossil fuels, which are finite and subject to depletion, renewable energy sources are sustainable and inexhaustible. Solar, wind, hydropower, and geothermal energy rely on natural processes that can be harnessed continuously without depleting the Earth’s resources.

Improved Air and Water Quality: Since renewable energy sources do not produce harmful air pollutants or contaminate water, their widespread use can lead to improved air and water quality. This has positive impacts on human health and ecosystems.

Technological Advancements: The development and implementation of renewable energy technologies drive innovation and technological advancements. Research and investments in renewable energy contribute to the creation of more efficient and cost-effective technologies over time.

Community Development: Localized renewable energy projects, such as community solar or wind farms, can contribute to community development. They provide a source of revenue for local communities, promote energy independence, and empower communities to take control of their energy resources.

Reduced Environmental Impact: The extraction, transportation, and combustion of fossil fuels have significant environmental impacts, including habitat destruction, air and water pollution, and soil degradation. Switching to renewable energy helps reduce these negative environmental effects.

Overall, embracing renewable energy is crucial for a sustainable and resilient future, addressing environmental challenges, promoting economic development, and improving the overall well-being of communities worldwide.
