请将以下这段话总结在3句话内，同时尽可能的保留主要信息： innovations like solar power，wind power，hydrogen fuel cells， and electric cars give us hope that we're not only reducing our dependence on fossil fuels, but we're also paving the way for sustainable futures. Although we're seeing exciting technological progress, the road to a fully sustainable energy system is still long and winding, with many challenges to overcome, including issues with storage, infrastructure, and regulation. The commitment from both the public and private sectors, as well as from individual citizens, will be crucial in ensuring this transition is successful and reaches all corners of the globe.
