Any source of energy that is superior in all aspects—cost, environmental impact, safety, and use of natural resources—does not exist. Therefore we need to develop a number of multiple revolutionary clean energy systems. Using the post-K computer, we will develop a method to conduct many simulations to assess various large-scale phenomena energy systems. These simulations will accelerate development of carbon-free coal gasification plants, low-cost, long-lasting fuel cells, large-scale wind power plants farm floating on the sea seashore, and nuclear fusion power plants.
