The world is undergoing a historic shift away from fossil fuels and toward renewable energy sources. Solar, wind, electric vehicles and other clean technologies are breaking records and becoming more affordable and accessible every year. The clean energy future is arriving faster than many people think, but more action is needed to achieve net zero emissions by 2050.
The United States, the world’s second-largest emitter of greenhouse gases, is leading the way in the energy transition. The country generated more electricity from renewable sources than from coal for the first time in 2020, and solar and wind power are projected to provide more than half of the nation’s electricity by 2035. The Biden administration has pledged to cut emissions by 50% to 52% below 2005 levels by 2030, and to reach 100% clean electricity by 2035.
“We are witnessing a tipping point in energy history and today’s commitment to large-scale carbon neutrality will help ensure that the tipping point is irreversible,” said Fatih Birol, executive director of the International Energy Agency (IEA).
The global picture is also encouraging. Investments in clean energy reached a record $501.3 billion in 2020, up 9% from the previous year, while investments in fossil fuel power fell by 20% to $132 billion. China, the world’s largest emitter of greenhouse gases, has committed to peak its emissions before 2030 and achieve carbon neutrality by 2060. India, the third-largest emitter, has set a target of installing 450 gigawatts of renewable energy capacity by 2030.
Technology innovation is a key driver of the energy transition, as it can reduce costs, improve performance, and create new business models for clean energy sources. A joint study by the European Patent Office (EPO) and the IEA shows that patenting activity in low-carbon energy technologies has increased significantly in the past decade, but more innovation is needed in some critical areas such as batteries, hydrogen and carbon capture.
“The next decade will be decisive for the future of our planet. We need to massively scale up innovation to address climate change while ensuring affordable and secure energy for all,” said António Campinos, president of the EPO.
The clean energy future is not only a matter of technology and economics, but also of social justice and human rights. The energy transition can create new opportunities for employment, health, education, and empowerment for millions of people around the world. However, it also poses challenges such as ensuring a fair and inclusive distribution of benefits and costs, addressing the impacts on workers and communities dependent on fossil fuels, and enhancing international cooperation and solidarity.
“The clean energy transition is not just about flipping a switch. It’s about making sure that everyone has access to affordable, reliable and sustainable energy. It’s about leaving no one behind,” said Rachel Kyte, dean of The Fletcher School at Tufts University.
The world is on the verge of a clean energy revolution that can transform our economy, society and environment. But we need to act fast and act together to make it happen. As Albert Cheung, head of analysis at BloombergNEF, said: “The economic recovery from Covid-19 offers an opportunity to invest in low-carbon infrastructure and technologies. But governments need to provide clear and credible policy signals to ensure that investors have the confidence to commit their capital.”
