There has been a considerable progress in setting up small-scale solar energy systems in urban areas. This could save the planet’s environment while completely altering the energy generation source of the earth. However, there are some difficulties on the road to this bright future from the most improbable sources.
Thin film solar cell efficacy records are bettered almost every other month and these cells are becoming very economical for production. Moreover, corporates are now considering the possibility of setting up solar panels that are not made of rigid frame or heavy glass. The panels are required to be lightweight, flexible, and durable for building integrated photovoltaics (BIPV) so that they can easily blend with the existing building materials.
The company Tesla is actively advertising its rechargeable battery, Powerwall, for storing the solar energy and soon is scheduled to launch its much awaited solar roof. More advancements are underway in producing efficient batteries such as solid-state and lithium air batteries. Moreover, there is increasing awareness about the future energy needs and current crisis. It is predicted that by 2050, around 70% of world population will reside in urban areas.
But there are possible obstacles that may stand in the way of the bright future. States, politicians, municipalities have gone public against people harvesting their own ‘free’ energy as it affects the revenue generated from different energy taxes. Also, lobbying power of both private and public electric utilities can hamper the progress. These corporates could completely perish if people start harvesting energy on their own and start trading it among themselves.
The possibility of a world without man-made CO2 emissions, a possible end to global warming and the prospect of producing electricity by everyone without much effort and is also cheap, reliable, and readily available is too good to put a stop on. The energy projects in the urban areas should continue its development and thus, pave the way for a brighter future.
