Can you imagine, the clean and renewable energy almost fully powering a large electricity grid? It may appear to be a distant dream. But a number of studies show that 100% renewable energy is possible with today’s technologies.
A study published by a group of researchers from the University of Delaware (UD) and Delaware Technical College (DTCC) claimed that by 2030, renewable energy could power a full-scale electrical grid a stunning 99.9%, and at close to today’s energy costs. The results destroy the conventional concept that renewable energy is too unreliable and expensive.
It can be achieved only by developing well-designed combination of wind energy, solar power, battery and fuel cell storage as the mixture could provide energy more than what actually requires at today’s electricity costs.
According to Professor Willett Kempton of theUniversityofDelaware, the main key is to get the right combination of electricity sources and storage and to calculate costs accurately.
The results were detailed in an online paper and will be published soon under the title “Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time”. In that, they have used a model with 28 billion combinations of storage schemes, and renewable energy sources. Each combination was tested over historical hourly weather data and electricity use over a four-year span.
The study assures that in future we can develop extra electricity to meet thermal loads.
