Renewable Energy—The Untold Drawbacks As the name suggests, renewable energy is derivation of energy from sources that are plentiful in nature. Physics states that energy cannot be created; it has to switch from another of its kind. Generating useful energy has to come from either burning fossil fuels, otherwise known as the non-renewable energy or through using the renewable sources. Fossil fuels such as coal, gas and petroleum comprise almost all of non-renewable sources. These are sources which cannot renew themselves at a rate at which they are being extracted. Industries and vehicles around the globe consume more (~80%) from this source than the renewable. Renewable energy, on the other hand does not have the fear to be depleted. These involve sunlight, rain, wind, waves and geothermal heat. Serving around 20% of global need in 2013, major electricity generated from green sources come from solar and hydroelectricity. Electricity is the chief of the four energy needs-- heating, off-grid solutions to rural and remote places and vehicle fuelling. The advantages of renewable are never ending as are their supply. But even supporters are aware of their short comings. When the world has vowed to go green, many may not respond to the disadvantages. Nobody talks of the steep initial cost of green generation. Green electricity’s construction cost reaches 2.5 times that of conventional generation. This is likely to go 33% more for wind farms (compared to coal-based generators) in 2015 as estimated by the Electric Power Research Unit. The producers could forget the high initial cost if the two productions were comparable. Renewable sources generate far less electricity than do coal and natural gas. However, they do not need fuels. They pose high inconsistence because of unpredictable weather patterns. Some sources need to be suited with the geographical locations, like solar intensity varies around the globe. Equally true with wind farms and hydro generators.

Hydroelectricity has recently faced global criticism as environmental issues are concerned. Shipping lines and river silting are also hampered. Wind farms are noisy and area consuming; and often harmful to bats and birds. Large-scale solar farms disturb natural ecosystem and scorch birds. Even after all these, the green technology is still too young for proper running. More R&D works are required for swift performance. Though maintenance cost is low for solar; hydro and wind farms need careful and continuous supervision/surveillance Talking of biofuel—they are alleged to cause indoor pollution, premature birth and deaths; and tuberculosis. The nuclear reactors are nonetheless detrimental. The Fukushima accident in one of Japan’s nuclear reactors still haunts the world. When good things go bad, they do it BADLY! The piece of writing does not criticize the recent Go Green movement around the globe; neither do we discourage clean generation. We clap at each renewable achievement while gently reminding that this scheme has hidden drawbacks. We just want to weigh all light-and-dark/cost benefit issues as we march on the new movement. We foresee a healthier world— environmentally and economically.
