Madrid is banning high-polluting vehicles from the city centre Kate Whiting 30 Nov All of these have also made solar less expensive than ever before. The efficiency of the solar panels made for rooftop solar have dramatically increased in efficiency over the past decade.
If this technology is scaled up, solar panels would require roughly half the space to produce the same amount of energy as the systems in place today due to their greater efficiency.
