  • Green energy or renewable energy goals are close to being met globally
  • In October 2024, the UK used its last coal power plant
  • Iceland is leading the way in renewable energy

Here in the UK, renewable or green energy is becoming increasingly normalised in everyday life. In fact, as of October 2024, the UK used its last coal power plant.

More people have solar panels on their roofs, and according to The Eco Experts’ 2024 National Home Energy Survey, 39% of more than 2,000 respondents have invested in solar panels and other low-carbon technologies, such as heat pumps.

Elsewhere, renewable energy is being used for some public transport, and just last year, we used more renewable energy on the grid than fossil fuel fuels during one quarter.

But there’s more than can be done to help combat the effects of climate change. Other countries across the globe are powering homes, businesses, and public transport off pretty much 100% renewable energy, which begs the question, is there anything we can learn from them?

The data we’ve used throughout this guide is based on government reports for each country, as well as research from the International Energy Agency (IEA).

It’s worth noting that many of the world’s leading renewable energy suppliers are also some of the most harmful countries for the environment. This can be confusing, and almost a catch 22 situation.

According to Statista, the top five countries with the highest renewable energy consumption are China, the USA, Germany, Brazil, and India. However, most of these countries are also pushing heavily for fossil fuels, and have no plan on changing that any time soon. In fact, China, America, Brazil, and India’s post-Covid-19 economic recovery plans were all rated as some of the most environmentally harmful in the world. 

There are other countries that are doing much better – countries that may not generate as much renewable energy overall, but are still sustaining their country in a much more eco-friendly way. We’ve decided to shine a light on these countries, and discuss what exactly they’re doing right. 

1. Iceland

Iceland is leading the way for green energy. Renewables have provided almost 100% of electricity production for this volcanic island since 2015, with about 73% coming from hydropower and 27% from geothermal power. Heating in homes and state buildings is also sourced from 99% geothermal sources.

Icelanders achieve this thanks to its 32 volcanoes scattered across the island, which is how they keep their homes toasty in the cold weather. Using highly advanced geothermal technology, scientists have developed ways to channel the heat generated from the ground into homes and state buildings. 

To power the majority of their electricity, Iceland harnesses the hydropower that is stored in ice caps and groundwater. The energy is created by evaporation, groundwater flow, and glacier flow. 

It seems as though more countries could seek inspiration from Iceland’s approach to green energy.

Iceland also features on the list of the top greenest countries in the world. Check out our page to find out what other countries are on there.

2. Norway

Ninety-eight percent of the electricity production in Norway comes from renewable energy – with hydropower being the key source.

Plus, to keep its citizens warm during colder months, Norway opts for the more eco-friendly source of bioenergy, rather than coal or oil. In fact, as of 2022, roughly 50% of heating was produced from waste incineration and about 20% from bioenergy. Oil and gas, on the other hand, only accounted for about 3% in 2022.

Car sales are also set to become even more eco-friendly. As early as January 2017, battery-powered cars and plug-in hybrids together accounted for more than 50% of all new car sales in Oslo.

While Norway hasn’t achieved 100% renewable energy operations, hydropower is now its main source at 92% and its goal is reduce climate emissions by 2030.

3. Costa Rica

The past five years have been incredible for renewables in Costa Rica, with its green power generation hovering around 99%, according to the latest updates. Take a look at the country’s renewable energy mix below:

ecoexp_flourish_chart

Data from Instituto Costarricense de Electricidad (ICE)

Renewable energy has not only benefited the environment here, but the people too. According to the Instituto Costarricense de Electricidad (ICE), renewable energy benefits 1.6 million households, 295 businesses, and 9,000 industries in Costa Rica. Overall, national access to electricity has surged from 14% in 1949 to almost 100% today. 

However, despite having nearly 100% renewable energy for its electricity production, around 70% of Costa Rica’s overall energy output still comes from oil and gas. These fossil fuels are used widely for transport and heating processes, as well as for activities like cooking.

To turn this around, Costa Rica has launched an economy-wide plan to decarbonise the country by 2050. Among other things, the new plan aims to modernise public transport – an industry that contributes to about 40% of Costa Rica’s climate change emissions – so this will be a huge step in the right direction.

4. Uruguay

Uruguay produces more than 97% of its electricity from renewable energy sources. Home to only about 3.39 million people, this small country has made it to the top five in wind and solar energy producers worldwide. 

Since the signing of the Kyoto Protocol in 1997 – which was hailed as the first major international climate change treaty – Uruguay’s renewable energy supply has grown by an incredible 93%. 

The key to this success? Wind. Between 2008 and 2017, Uruguay went from having virtually no wind power to nearly 4,000 megawatts of installed capacity. As a result, carbon emissions have fallen by roughly 20% from their 2012 peak.

The future of renewables in Uruguay also looks like a bright one. The country is implementing a pilot project to explore the use of clean hydrogen in long-distance and heavy-duty transportation. In theory, this will continue to decarbonise the transport sector – one of the most polluting industries in the world. 

The government plans on continuing this diversification of renewable energy, focusing on energy efficiency, self-sufficiency, and promoting research in new technologies.

5. Kenya

Two years ago, Kenya’s government pledged that its electricity generation mix would be made up of 100% renewable energy by 2030. At the time, the country’s energy consisted of roughly 77% green energy – which has since jumped to 93%. The majority of its total 2.7 GW installed capacity comes from hydropower (677 MW) and geothermal energy (690 MW). 

Plus, like many other developing countries that are using renewables, the amount of people who now have access to electricity has soared over the years. In 2022, 76% of the population had access to electricity.

Kenya is broadening its horizons with even more diversification of its grid. One of the more recent projects in the country involved setting up Africa’s largest wind farm (310 MW), which connected to the grid in October 2019 and is set to provide another 20% of the country’s installed electricity capacity.

6. Scotland

Scotland is aiming to reach the equivalent of 50% of its total energy demand, including electricity, transport and heat, to be supplied by renewable energy by 2030.

Data from gov.scot

The Scots have been pushing for more renewable energy year-on-year: in 2016, 54% of Scotland’s electricity came from renewables; in 2017, this rose to 68.1%; and in 2018, it reached a whopping 74.6%. 

There are plenty of projects in the pipeline to continue this green growth in Scotland, too – so far, the Wave Energy Scotland (WES) technology programme, which is entirely government funded, has invested more than £30m in over 80 projects.

Scotland will also be investing a huge amount of money into the decarbonisation of roads by promoting the use of ultra-low emission vehicles (ULEVs), while also phasing out new petrol/diesel cars and vans eight years ahead of the UK Government’s 2040 target.

7. Nicaragua

This tiny, Central American country has kick-started the new decade with a bang. In the first few days of 2020, renewable energy accounted for around 81% of total electricity generated. Check out Nicaragua’s energy mix below:

One of the main reasons Nicaragua introduced renewables to its energy mix was to increase general access to electricity. As a result, the country finished 2019 with a coverage of 97.16%, benefitting more than 3.4 million Nicaraguans

Nicaragua’s state-owned electric power company Enatrel, announced plans for the implementation of 12 programs to further increase renewable energy across the country – backed by an investment of $348.4m. These programs include renewable energy generation, rural electrification, introduction of more solar panels, obsolete network rehabilitation, and a broadband installation program.

8. Sweden

Renewable energy in Sweden currently accounts for 54% of its overall energy mix. After reading this list, that might seem a little underwhelming – but hear us out. 

Sweden has become the first country in Europe to meet the renewable energy targets set by the EU, eight years ahead of schedule.

Sweden’s low carbon emission rate is mostly down to the fact that about 80% of electricity production comes from nuclear and hydroelectric power. Nuclear power remains a topic that divides opinion, since it’s classed as a fossil fuel, but is more ‘low-carbon’ than coal and oil. 

The main challenges that lie ahead for Sweden now include having 100% renewable electricity generation by 2040, and reducing transport emissions by 70% between 2010 and 2030. And, with its highly decarbonised power system already in place, the country is well on its way to meeting these goals. 

9. Germany

As it stands, Germany’s energy mix currently consists of 54% renewables. In comparison to the rest of this list, that might not seem so impressive – but we think it’s important to bear in mind that this is Europe’s biggest economy we’re talking about.

*The different shades of green represent the various renewable sources in the energy mix, whereas the different shades of red represent the fossil fuel sources 

By 2030, we can expect to see Germany’s renewables jump up to 65% in its power mix, and hopefully up to 100% by 2050. This will be brought about by abandoning nuclear energy by 2022, and plans for a long-term exit from coal.

The key thing that puts Germany on this list is its commitment to a green recovery post-Covid-19. The German government has unveiled plans for a massive €130bn stimulus package that features at least €40bn of climate-related spending. 

Chancellor Angela Merkel’s plan has been praised as one of the best recovery stimuli in the world. Its sweeping ambitions to boost electric vehicle sales, improve building-energy efficiency, enhance public transport networks, develop hydrogen infrastructure, and shift the cost of renewables subsidies onto general taxation is sure to improve Germany’s carbon footprint massively.

The top three countries that generate the most wind energy are China, America, and the UK. As we stated in our methodology, some of the world’s biggest renewable energy generators are also some of the more harmful – and that’s certainly the case with wind generation. 

Check out the chart below to compare the top 10 countries producing the most wind energy:

Similar to wind generation, the top countries producing the most solar energy are China and America, who are followed this time by Japan. 

ecoexp_flourish_chart

Data from Statista

There are three countries that overshadow the rest of the world when it comes to fossil fuel consumption: China, America, and India. In fact, these three countries use more fossil fuels than the rest of the world combined! 

Together, these countries make up 54% of the world’s fossil fuel consumption, according to the Global Material Flow Database. You can compare them to the rest of the world on the map below.

The world’s leading green energy countries have found ways to utilise their natural surroundings to benefit both their citizens and the environment. We can all learn a lot from these nations.

Whether the country is surrounded by volcanoes to create geothermal energy, lots of sunshine to generate solar energy, or breeze to produce wind energy – there are ways we can all use nature to power our cities and towns. 

The amount of fossil fuels on this planet are finite, and we’re running out of time to make the switch to renewables – but these countries prove that it’s possible. Let’s follow in their footsteps. 

  • The top countries producing the most solar energy are China and America, who are followed this time by Japan
  • The world’s leading green energy countries have found ways to utilise their natural surroundings to benefit both their citizens and the environment
  • Sweden has become the first country in Europe to meet the renewable and green energy targets set by the EU, eight years ahead of schedule
  • By 2030, we can expect to see Germany’s renewables jump up to 65% in its power mix, and hopefully up to 100% by 2050
  • Thirty-nine percent of more than 2,000 respondents have invested in solar panels and other low-carbon technologies, such as heat pumps
