Unlike fossil fuels, solar energy systems do not emit greenhouse gas or air pollution, which makes solar power one of the best potential solutions to the climate crisis. But the modern solar cell wasn’t invented until the mid-1900s.
Humans have used solar energy since around the 7th century BC, when they used sunlight and glass to ignite fires. “I personally think that with the low cost of solar and wind, ample land area in the US and some appropriate government policies, this transition can come fast.”ĬNN spoke with energy transition experts about the most reliable energy sources – and their challenges – to replace coal, oil and gas and halt the climate crisis. “Once the population begins to understand that it is possible to (live) without fossil fuels, it will be easier because then they will demand the local constituencies or local bodies to push for cleaner sources,” Modi told CNN.
As climate change fuels more extreme weather events, and environmental disasters threaten wildlife and human health, more people are banking on clean, carbon-free energy to speed the world’s transition away from fossil fuels and slow global warming.Įnding the planet’s reliance on fossil fuels is critical to curbing the climate crisis, but Vijay Modi, a professor of mechanical engineering at Columbia University, said there are still hurdles to overcome before we can fully transition to renewables: energy storage, public acceptance of transmission lines and adoption of electric vehicles and alternative home heating.
