Obstacles to entering the household and SME energy markets include capital-intensive infrastructure and process automation necessary to handle large numbers of low volume consumption orders. Current service models do not provide direct connection between producers of renewable energy to consumers, resulting in the inability to profit and grow business, save, and choose between renewable and fossil fuels. Government subsidies for renewable energy are designed to jumpstart markets until the necessary economies of scale for grid parity are reached, but in reality, there are very few countries where renewable energy has reached grid parity.
