Clean energy may offer a more environmentally friendly outcome than fossil fuels. However, clean energy is beset by uncertainties when the sun does not shine through and the wind does not blow. Worse still, science has not yet overcome scalability issues that are compounded by lack of technological knowhow on how to store solar and wind energy. The electrical “green-outs” of August 2020 in California are a reminder that without storage facilities for clean energy, utilities are driven to spot markets for electricity rendered from traditional sources of energy as economic setbacks occur due to compromised supplies of electricity. Without means of energy storage, new technology cannot fully replace the old. One can only hope that the dream to build a future based on renewable energy will lead to discoveries that will overcome scalability and storage issues.
