Between 2007 and 2017, the volume of renewable energy produced in the European Union’s 28 member states rose by 64%.

That energy comes from diverse sources, from the burning of wood and biomass to wind, geothermal and solar.

In countries across the continent, renewable energy is providing an increasing share of the power mix – the top five nations for renewables as a share of consumed energy are Sweden (54.5%), Finland (41.0 %), Latvia (39.0 %), Denmark (35.8 %) and Austria (32.6 %).

Here are some of the projects helping the EU pave the way to a sustainable energy future.

1. Floating power

The Rhône is one of Europe’s most important rivers. It flows from the Swiss Alps to the Mediterranean, and gives rise to some of the best-known wines produced in France. Now the Rhône valley is a renewable energy hotspot, too – it’s home to Europe’s largest floating solar power plant.

The 17 megawatt (MW) facility sits in what was once a quarry, which has since been converted into a lake. Its annual output will be enough to power 4,733 homes.

The project has been configured with community ownership in mind; local citizens were invited to invest in the plant, thereby becoming stakeholders in its future success.

2. Communal wind

Community ownership plays a major role in renewable energy projects in Denmark, too. Just off the coast of the country’s capital, Copenhagen, lie the 20 turbines of the Middelgrunden offshore wind farm.

When Middelgrunden was built in 2000, it was funded by investment from the people – around 8,500 Danish citizens bought shares, raising more than $25 million and taking a 50% stake in the plant.

The collective ownership model is not unique in Denmark. But this pioneering move to use it in the production of energy has taken root. Now, all new wind farms in the country must be at least 20% community-owned.

What's the World Economic Forum doing about the transition to clean energy?

Moving to clean energy is key to combatting climate change, yet in the past five years, the energy transition has stagnated. Energy consumption and production contribute to two-thirds of global emissions, and 81% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago.

Effective policies, private-sector action and public-private cooperation are needed to create a more inclusive, sustainable, affordable and secure global energy system.

Benchmarking progress is essential to a successful transition. The World Economic Forum’s Energy Transition Index, which ranks 115 economies on how well they balance energy security and access with environmental sustainability and affordability, shows that the biggest challenge facing energy transition is the lack of readiness among the world’s largest emitters, including US, China, India and Russia. The 10 countries that score the highest in terms of readiness account for only 2.6% of global annual emissions.

To future-proof the global energy system, the Forum’s Shaping the Future of Energy initiative is working with projects including the Partnering for Sustainable Energy Innovation, the Future of Electricity, the Global Battery Alliance and Scaling Renewable Energy to encourage and enable innovative energy investments, technologies and solutions.

3. Colossal turbines

Imagine a wind turbine so large, so powerful, that a single rotation of its propeller could supply an average-sized home with all its electricity for a day.

For the residents of the Scottish city of Aberdeen, this vision is becoming a reality – 11 such turbines are being built just out to sea, making up the European Offshore Wind Deployment Centre (EOWDC).

Each of the 8.4 MW structures is 191 metres high – they’re the world’s most powerful wind turbines, according to Vattenfall, the energy firm that built them under a scheme part-funded by the EU.

Built at a cost of more than $380 million, the EOWDC will generate enough power to meet more than 70% of Aberdeen's domestic electricity needs, and almost a quarter of its total demand for power.

4. Chernobyl solar

In April 1986, fires and explosions broke out at the Chernobyl nuclear power plant in Ukraine. The resulting radioactive contamination affected an area of almost 30,000 square kilometres, which contained around 5 million people.

The site was eventually closed to the outside world and its name became synonymous with the dangers of a nuclear accident. But now, new life has been breathed into the area – and new energy, too.

A 1 MW solar plant, comprising 3,800 panels, has been built at a cost of $1.2 million, by Ukrainian energy and construction company Rodina and German energy firm Enerparc. The plant will produce enough energy to power 2,000 apartments.
