Renewable Energy Could Reshape The Future


Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. In addition, an energy from a source that is not depleted when used, such as wind or solar power.

Today mostly used energy source is Fossil fuels

that are non-renewable, that is they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, the many types of renewable energy resources such as wind and solar energy are constantly replenished and will never run out. The Union of Concerned Scientists suggest the following clean renewable energy sources which can be identified globally. Wind Power, Solar Power, Biomass, Geothermal Energy and Hydroelectric Power.

Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels which are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.

In South Asia, a number of developing countries like India, Pakistan, Sri Lanka, Bhutan, Nepal, Afghanistan and Maldives are looking into inexhaustible and repeatable alternative energy sources such as solar, wind, hydro and biomass.

Developed countries have good renewable energy resources, including solar energy, wind power, geothermal energy, and biomass. Investments in renewables can be less expensive than fossil fuel energy systems.

Iceland is currently the only country in the world that obtains 100% of its energy from renewable resources, with 87% of it’s from hydro-power and 13% from geothermal power. Costa Rica is among the top renewable energy users, with 99% of its electricity needs coming from hydroelectric, geothermal, and wind. Iceland. Iceland generates the cleanest electricity per person on earth, with almost 100% of its energy coming from renewable sources that make the most of its unique landscape.

Fossil fuels are non-renewable which they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, the many types of renewable energy resources such as wind and solar energy-are constantly replenished and will never run out. The burning of coal for energy also produces many different types of particulate matter that pollute the air. When one factors in the various non-financial costs of fossil fuel use such as pollution, climate change, and the impact on biodiversity, renewable energy is actually far more efficient than fossil fuels.

One major advantage with the use of renewable energy is its sustainability and will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation. Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing and installation

One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities. It also indicates that the best solution to our energy problems may be to have a balance of many different power sources.

Another disadvantage of renewable energy sources is the reliability of supply. Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity. When these resources are unavailable so is the capacity to make energy from them. This can be unpredictable and inconsistent. The current cost of renewable energy technology is also far in excess of traditional fossil fuel generation. This is because it is a new technology and as such has extremely large capital cost.

Global Warming is rapidly increasing day by day its due many reasons but burning of fossil fuel has been one of the key problems therefore the solution to bring back the control over the temperature raising is that it’s time to go for an energy transitions. I strongly believe that this could reshape the future of this world.
