WHAT IS RENEWABLE ENERGY?




Renewable energy, also known as clean, green or sustainable energy, is energy powered by natural resources that we as a planet have an endless supply of. For example, Solar energy is energy generated through sunlight. As the sun continues to shine we will always have a source of sunlight to generate this green energy from. While green energy is often seen as a modern technology, we have been using natural resources for energy for a long time now. For example, using the sun’s heat to start fires, or dry clothes, and wind to power sails and windmills.

In this blog post, we will look at the reasons why renewable energy is so important to our future.




SO WHAT IS THE OPPOSITE OF RENEWABLE ENERGY?


Non renewable energy, or dirty energy, is energy generated through burning fossil fuels such as oil, gas and coal. In 2019, non-renewable fuels supplied around 80% of the world’s total energy. Unlike natural resources, fossil fuels are predicted to run out within the next 40-60 years, therefore finding an alternative source of energy is essential. Burning fossil fuels contributes heavily to global warming, as they create greenhouse gases and pollutants which are dangerous to both our ozone layer and respiratory health. Carbon dioxide emissions from burning coal alone, account for 44% of the world’s total.

Using fossil fuels can endanger both humans and the environment. From large oil spills to flames, non-renewables pose a threat to both human/animal health and life. As they are accessible by destroying land to mine.




WHAT ARE THE ADVANTAGES OF RENEWABLE ENERGY?


1. RENEWABLE ENERGY WILL NEVER RUN OUT


As opposed to using finite resources that damage the planet and are non-renewable resources, Renewable energy sources are abundant in nature. As renewable energy takes environmentally friendly forms such as Solar energy, Hydroelectric, and Wind Power, they are all resources that we have an infinite supply of!


2. RENEWABLE ENERGY IS BETTER FOR OUR HEALTH


Causing no air pollution and working with the planet, renewable energy also known as clean energy is better for our health. In a year, the UK produces a total of 414.1 million tonnes of carbon dioxide, causing a rise in air pollution-related deaths. Approximately, 28,000 – 36,000 early deaths each year are the direct result of air pollution in the UK. By moving to 100% renewable energy by 2050, we can reduce CO2 emissions by 70%. By switching to renewable energy sources we can reduce the amount of CO2 produced and thereby reduce the number of air pollution-related deaths.


3. RENEWABLE ENERGY IS BETTER FOR THE ENVIRONMENT


By diversifying our energy supply through renewables we are reducing our dependence on fossil fuels which contribute towards global warming. The climate impact Global warming has goes beyond humans, it also affects nature’s ability to survive and blossom. Instead of using fossil fuels for which we dig and destroy ecosystems, renewable energy sources are sustainable and clean forms of energy.


4. RENEWABLE ENERGY IS A GREAT ECONOMICAL INVESTMENT


Yes, renewable energy is not only good for the environment but also has economic benefits. For example, its ability to support employment. The renewable energy industry creates a significant amount of jobs worldwide. According to the IRENA, in 2017 there were 10.3 million people employed within the renewable sector. And this is only set to rise.

Used to provide both electricity and heating into your homes, renewable energy is a cheaper and kinder alternative to fossil fuels. Renewable energy such as Solar energy, also can provide electricity domestically up to 70% cheaper. Although the upfront cost of many renewable energies is expensive, once implemented they are cost-effective with little maintenance. In addition, as renewable energy sources are available in all corners of the world, they don’t need importing. Saving further money and carbon emissions.




RENEWABLE ENERGY EXAMPLES

We can combat the problem of unsustainable energy sources by considering different types of renewable energy. Renewable energy comes in many forms, each utilising the natural elements of the world around us. Examples of Renewable Energy Include:


Solar Energy: Renewable energy is made by converting packets of energy from the sun into electricity.


Wind Energy: Renewable Energy generated by utilising wind power. The wind’s energy turns the blades of a turbine which in turn powers a generator to make electricity.


Hydropower Energy: Renewable Energy is generated using kinetic energy from flowing water as it moves downstream. Essentially using water to power your homes.


Geothermal Energy: Renewable energy is generated using heat trapped in the soil and stones below the ground.


Biomass energy: Renewable energy generated or produced from materials such as plants, wood, and waste. It is the best way to get rid of your waste, by recycling it into energy to power your home and decreasing the litter sent to landfill sites.
