This is something a growing number of states across the U.S. All can help us make the transition to low-cost, carbon-free power. What will be required in the years ahead is a diverse and flexible mix of energy solutions-a Swiss army knife of energy tools-to support a future of renewable energy generation to meet our needs. While I wish there could be a single, magic bullet solution to this problem, there isn’t one right now. To reach zero carbon emissions, however, we need to find a way to use more clean energy sources as a backstop. Usually, you back up renewable sources with fossil fuels like natural gas that can quickly and reliably provide power when it’s needed. We need big breakthroughs in technologies that will allow us to supply the power grid with clean energy even during windless days, cloudy weather, and nighttime. The second challenge is probably less obvious and more difficult. And thanks to falling prices for solar panels, wind turbines, and other technologies, deploying renewable energy systems is more affordable than ever before. We need to do more to harness the power of the sun and wind. The first challenge will come as no surprise. So, what will it take to reach the goal of zero carbon electricity generation? Think electric cars and buses emission-free heating and cooling systems in our homes and businesses and energy-intensive factories using more clean power to make products. We’ll unlock a source of carbon-free energy to help power the sectors of the economy that produce the other 75 percent of greenhouse gas emissions, including transportation, buildings, and manufacturing.
With clean electricity, we can do more than light our homes and power our grid. Here’s why: While electricity generation is the single biggest contributor to climate change-responsible for 25 percent of all greenhouse gas emissions and growing every day-it’s an even bigger part of the solution. This would be an incredible achievement and the most important step we can take to prevent the worst impacts of global warming. By investing in energy innovations, we can build on the progress we’ve made deploying current technology like renewables, which will help accelerate the transition from fossil fuels to a future of reliable and affordable carbon-free electricity. This is great news.Īnd here’s better news: We can do even more. Wind and solar power generation is expanding around the globe at record rates, allowing more people to get their electricity from clean, renewable sources than ever before.
