Renewable energies (or renewables) are ways to generate energy from (theoreally) unlimited natural resources. These resources are either available with no time limit or replenish more quickly than the rate at which they are consumed.

Renewable energies are generally spoken of as opposed to fossil fuel energies. The fossil fuels’ stocks are limited and non-renewable in the human timescale. The most known examples of these resources are coal, oil or natural gas. On the contrary, renewable energies are produced from renewable sources. Here, we’re talking about energy coming from solar rays, wind or water cycles – all theoreally unlimited on a human scale time.

Renewable energies are also often referred to as “green energies” or “clean energies”. Still, this doesn’t mean that these energies aren’t harmful to the environment and have zero impact. Nonetheless, they have a low environmental impact compared to fossil fuels. That’s why they’re increasingly becoming important elements in companies’ CSR strategies in terms of sustainable development.

There are several types of renewable energies that are produced by different sources such as the sun, wind or water. In fact, these renewables’ power consumption has been growing over the last year. They have provided 8% of the world’s electricity in 2017 and they now cover 1/3 of the power mix in Europe. At the same time, the energy grid gets 1/4 of the total energy in China and 1/6 in the United States, India, and Japan. Let’s learn more about them below.

Is Solar Energy Really Green And Sustainable?

1 – Solar Energy

solar energy power plant renewable
This type of renewable energy comes directly from the capture of solar radiation. Here, the solar radiation is absorbed by specific sensors and rebroadcasted following 2 possible operation modes:

Capturing sun rays and directly converting them into energy through photovoltaic solar panels;
Capturing, collecting and turning the sunlight into heat that warms up water or air.

Examples of Solar Energy in the World

It’s estimated that in 2017 1,6% of the worldwide generated energy came from solar sources. At the same time, solar power also contributed to 20% of the total energy growth in this same year. Some of the most known sources of solar energy are:

The Kurnool Ultra Solar Park in India. It has a total generation capacity of 1000MW and over 4 million solar panels installed;
The Longyangxia Solar Park in China that has a total capacity of 850MW and covers around 25sq km.
The Kamuthi Solar Facility in India: it has a total capacity of 648MV and covers 10sq km.

Is Solar Energy Renewable or Nonrenewable?

Solar energy is inexhaustible in the sense that it will cease once the solar system’s star – the sun – dies. However, many people wonder if, from a perspective of human’s being able to capture and use solar energy in the long-term, whether solar energy is renewable or nonrenewable.

[Full answer available soon.]

2 – Windpower, a Renewable Energy

Wind power is another renewable energy. Here, the wind’s kine energy makes turbines spin and creates a mechanical movement. Afterward, a generator transforms this mechanical energy into electricity. There are several types of wind renewable energies: onshore wind turbines, off-shore wind turbines and even floating wind turbines. But the operating principles are basically the same for all these types of wind-generated energy.

Examples of Wind Power in the World

Wind power continues has also been growing, In fact, it provided 4.4% of global power generation in 2017. The highest installed wind capacity belongs to China (164GW). At the same time, in the EU, wind power provides 15% or more of the energy generated in several countries such as Germany, Portugal or Lithuania. Some of the most known sources of wind power energy are:

The Gansu Wind Farm in China. It is still under construction and it will be able to produce 20,000MV of power by 2020;
The onshore Muppandal Wind Farm in India with a capacity of 1,500MW and over 3000 turbines;
The Alta Wind Energy Center in the U.S. with a total capacity of 1,548MW that’s expected to reach 3,000MW by 2040;
The Walney Extension in the UK. It has a total capacity of 659MW and it’s the world’s largest offshore farm.

3 – Hydro-Electric Power

Hydro-electric power consists in the transformation of the kine energy of the water (from rivers, dams, marine currents or tides) into mechanical energy by turbines.

- Marine energies: what is it?
- 5 promising marine energy projects
- The tidal energy: an example of the tidal turbine DCNS

Examples of hydro-electric power in the world

The Sihwa Lake Tidal Power Station in South Korea. This is the world’s biggest tidal power installation and it has a capacity of 254 MW;
The Rance Tidal Power Station in Brittany, France, has a 240 MW capacity;
The Three Gorges Dam in China is the world’s largest power station in terms of installed capacity (22,500 MW).

4- Biomass

biomass renewable energy definition
Biomass is made up of organic materials from plants or animals that contain stored energy. The combustion of these natural materials produces renewable energy. Some examples of generating energy from biomass are:

Directly burning solid biomass garbage or wood to produce heat;
Converting biomass into biogases such as methane or CO2 due to the bacterial activity that happens in the absence of oxygen (as is the case in landfills);
Using sugar or corn crops to create biofuels such as bioethanol or biodiesel and mixing them with fossil fuels afterward. As a matter of fact, the world’s biofuels production increased by 3.5% in 2017.

- What Is Biogas Energy Production?

Examples of Biomass Energy in the World

Some of the most known biomass power plants in the world are:

The Iron Bridge power station in the UK, with a capacity of 740MW. It uses wood pellets as the main fuel;
The Alholmenskaft power station in Finland. It has a 260MW energy generation capacity;
The Polaniec power plant in Poland that uses mainly agricultural by-products and wood residues. It has a 205MW capacity.

5- Geothermal Power as a Renewable Energy

geothermal energy renewables definition green
The Earth generates and stores geothermal energy. In other words, radioactive materials decaying inside the Earth are emitting energy. Electricity can be created using directly or indirectly this energy, depending on the technology implemented. There are 3 main ways to use geothermal energy:

Generating electricity directly from the Earth’s heat;
Producing heat directly from hot water boiling on the planet’s surface;
Using pumps over the shallow ground to heat (and also to cool)

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

Most journeys in Britain and the US are made by road. Some of these are made on public transport but most are by private car.

In Britain many people rely on their cars for daily local activities, e.g. getting to work, doing the shopping, and visiting friends. People living in urban areas may use buses, trains or, in London, the Underground, to get to city centres, mainly because traffic is often heavy and it is difficult to find anywhere to park a car. Some places in the country may have a bus only two or three times a week so people living there have no choice but to rely on their cars.

In the US large cities have good public transportation systems. The El railroad in Chicago and the underground systems of New York, Boston, San Francisco and Washington, DC are heavily used. Elsewhere, most Americans prefer to use their cars. Families often have two cars and, outside major cities, have to drive fairly long distances to schools, offices, shops, banks, etc. Many college and even high-school students have their own cars.

Long-distance travel in Britain is also mainly by road, though railways link most towns and cities. Most places are linked by motorways or other fast roads and many people prefer to drive at their own convenience rather than use a train, even though they may get stuck in a traffic jam. Long- distance coach/bus services are usually a cheaper alternative to trains, but they take longer and may be less comfortable. Some long-distance travel, especially that undertaken for business reasons, may be by air. There are regular flights between regional airports, as well as to and from London. A lot of freight is also distributed by road, though heavier items and raw materials often go by rail.

In the US much long-distance travel is by air. America has two main long-distance bus companies, Greyhound and Trailways. Amtrak, the national network, provides rail services for passengers. Private railway companies such as Union Pacific now carry only freight, though in fact over 70% of freight goes by road.

The main problems associated with road transport in both Britain and the US are traffic congestion and pollution. It is predicted that the number of cars on British roads will increase by a third within a few years, making both these problems worse. The British government would like more people to use public transport, but so far they have had little success in persuading people to give up their cars or to share rides with neighbours. Most people say that public transport is simply not good enough. Americans too have resisted government requests to share cars because it is less convenient and restricts their freedom. Petrol/gasoline is relatively cheap in the US and outside the major cities public transport is bad, so they see no reason to use their cars less.

According to the passage, people in Britain refuse public transport because ______.

A. they like to share rides with neighbours

B. they think it is not good enough

C. they see no reason to use their cars less

D. petrol is relatively cheap in Britain
