The innovative corporations of energy generation


Aarhus, Denmark


vestas logoIn terms of sustainable energy, not much needs to be said about Vestas, one of the leading players in the wind energy industry. To date, the company has installed over 77,000 wind turbines in 83 countries with a combined capacity of over 132 GW. This capacity has enabled Vestas to avoid the release of more than 1.3 billion tonnes of CO2.

Nevertheless, the company aims to further increase its actions in the fight against climate change by fully embracing sustainability in every aspect of its organization. “Integrating sustainability into everything we do is a part of our vision to become the global leader in sustainable energy solutions,” said Lisa Ekstrand, Senior Director and Head of Sustainability at Vestas.

To accomplish this, Vestas has focused on four main points, starting with achieving carbon neutrality without offsets by 2030. Its first steps are to transition 35% of its corporate cars to electric vehicles or plug-in hybrids, including 127 sustainably fuelled service vehicles. By 2025, Vestas aims to transition its entire corporate fleet to zero-emission vehicles. As part of its carbon neutrality drive, the company is also committed to reducing its supply chain CO2 impact by 45% per MWh generated by 2030.

Vestas also aims to introduce a zero-waste wind turbine design by 2040. Currently, the company’s wind turbines have average recyclability of 85% due to non-reusable composite materials. Vestas aims to incrementally improve this rate, increasing its recyclability from 42% to 50% by 2025 and 55% by 2030.

The company is also developing a new waste management strategy based on implementing circular economy principles in various stages of its value chain. A long-term goal of the company is to lead the transition towards a world powered by renewable energy. To this end, Vestas has focused on developing power-to-x technologies, including hydrogen and e-fuels solutions.

To this end, the company joined the Getting to Zero Coalition in 2019, an initiative developing methods to reduce CO2 emissions in the shipping sector, and partnered with Mercedes-Benz in the Formula E Championship to promote electric transportation solutions.

Solna, Sweden


vattenfall logo

As a large producer of renewable energy, power producer Vattenfall is committed to incorporate sustainable practices across their whole value chain. Since its inception in 1909, the Swedish company established a presence in the Scandinavian region and countries such as Germany and the United Kingdom, generating and providing power using several different methods.

As part of their commitment to eliminate fossil fuel use within one generation, Vattenfall is incorporating sustainable energy systems and practices through different initiatives in renewable production and climate-smart energy solutions for their customers. Vattenfall is focusing on multiple targets that address the climate change challenge, starting with the reduction of greenhouse gas emissions.

They aim to reduce 38% of Scope 1 and 2 GHG emissions by 2030, and 20% of absolute Scope 3 GHG emissions from the use of sold products by 2030. As their first steps towards reaching these targets, Vattenfall is adopting smart energy solutions across three projects, aiming to make the city of Uppsala more sustainable.

The consequence of these projects will be the reduction of GHG emissions from 360,000 tonnes to about 140,000 tonnes or well over 50%. Outside of this, Vattenfall will also reduce their NOx, SO2, and dust emissions by incorporating several practices, like shifting to biomass, converting coal-fired power plants into gas-fired plants, and using different measures for reducing combustion emissions on current coal fires power plants.

In addition to tackling climate change, Vattenfall is set to achieving its ambition of becoming a circular business by 2030. Sustainable resource management is a key part of this goal, causing the power producer to strive for optimization of resource use across all parts of their operations. Examples that encompass these claims are their ongoing initiatives to produce green hydrogen, with the most prominent one being their collaboration with Preem.

Through this partnership, both companies want to incorporate fossil-free hydrogen for large-scale biofuel production. As a result, more than 12.5 million tonnes of CO2 emissions are projected to be reduced, corresponding to about 20% of Sweden’s total emissions.

Tempe, USA

First Solar

first solar logo

Tempe-based First Solar is one of the largest providers of utility-scale photovoltaic (PV) power plants and solutions. Since the end of 2019, the company’s manufacturing capacity has reached 5.5 gigawatts, with 25GW of their modules generating electricity to power more than 12 million average homes. Furthermore, they displace over 17 million metric tons of CO2e per year and save 45 billion liters of water.

Along with these impressive metrics, First Solar is committed to improving its sustainability strategy by incorporating more practices and initiatives across its value chain. Through the Sustainability Policy, First Solar is dedicated to addressing challenges and goals in the environmental, economic, and social areas of their company.

As part of their goal to reduce their GHG emissions intensity per watt produced by 2021, the company incorporated several practices like increased module efficiency and manufacturing throughput, as well as installed onsite PV installations at their production facilities in Ohio and Malaysia, and their recycling facility in Germany. This enabled them to reach their 2021 goal three years early, with their GHG emissions being intensively decreased by 40%.

Another example of their dedication towards environmental challenges is manufacturing water intensity. Since 2009, First Solar achieved a 64% decrease in this, mostly as a result of the significant improvements in module efficiency, manufacturing throughput, and implementation of water conservation and recycling projects across their operations.

Furthermore, all of their facilities generate zero wastewater discharge under normal operations. Having a longstanding position in PV recycling, it is obvious for First Solar to aim at incorporating a circular economy model across their operations.

Ever since the initialization of their global PV module recycling program in 2005, the company has been investing in improvements in the PV recycling technology, leading them to a process that recovers high-mass fraction materials such as glass and frames with more than 90 mass-%.

One notable example of this recycling technology is in their facility in Malaysia, where the recovered laminate material is reused in rubber products. As a result, one kilogram of First Solar’s semiconductor material can be reused 41 times over, which translates into a use time of more than 1,200 years. On the other hand, the remainder of the recycled module scrap that cannot be used in secondary raw materials is handled properly using several responsible waste treatment and disposal techniques.

Energy generation for a green tomorrow and a sustainable future

It is clear that the world is slowly waking up to the fundamental issue that is climate change, and small steps to decarbonize our energy supply are slowly being taken. However, nowhere near enough is being done to tackle the problem seriously, and we must not rest on our laurels. 

Even though renewable energy production is continuously rising, the world remains in a precarious position. According to the IEA, fossil fuel demand will continue to grow in 2021, with coal alone increasing by 60% more than the total renewable capacity. In turn, this would raise emissions by nearly 5%. If we intend to develop a sustainable future truly, this bleak situation must not repeat in the coming years. 

Thankfully, innovative companies have taken the mantle to tackle the problem, developing breakthrough new technologies and solutions, which promise abundant renewable energy for a sustainable future. By shifting the focus from governments to the private sector, corporate innovation is set to tackle green energy production in a more agile environment. This enables companies to place sustainability as a core tenet of their business, leveraging the free market to develop a better world and a green tomorrow.
