Sustainability expert, Chris Goodall, shares his thoughts via Mega.Online in a new video on how the power of the sun could continue to drive global energy use and change the world. The video interview with Goodall, author of The Switch, focuses on why cheap solar panels and advancements in storage technology are about to transform our world. By 2030 or 2040 solar will be the cheapest way to generate electricity, indeed any form of energy EVERYWHERE. At the rate of growth that we are seeing at the moment of 35-45% per year solar will grow from providing 2% of global electricity to at least 50% by 2030. We can see the cost of batteries coming down in price dramatically. Turning surplus solar electricity generating during the summer into something we can put into natural gas networks is what we should be looking at in the UK. Generating hydrogen from water and merging it with carbon dioxide is the simplest way to do this using microbes. These then excrete methane. The era of fossil fuels is drawing to a close.
