Renewable Energy: A Paramount Solution for Fighting the Climate Change


Historically, energy has been the cause of numerous conflicts. Access to petrol has generated deadly wars and a split between producer and consumer countries, incarnated since the past three decades by the rival organizations. There is no such global organization as far as nuclear energy is concerned.

Founded on 26th January 2009 in Germany, the International Renewable Energy Agency (IRENA) is a real breakthrough. IRENA is the agency of reconciliation of all countries to form a sacred union for a global fight; the transition to clean energy. Majority of the nations have joined the movement and have reached a consensus to minimize the usage of fossil fuels. This has occurred at a time when the IPCC, presided by an eminent Indian renowned scientist has launched works that will conclude with the publication of a report on renewable energy within a year.

Today, renewable energy represents 18 percent of global energy consumption. This is mainly constituted of traditional biomass; women in developing countries who use wood for cooking and hydraulic energy. But other forms of renewable energy, such as wind and solar energy, have witnessed very strong growth rates, which is more than twenty percent per year over the last decade for the former, and an even higher growth rate for the latter.

As renewable energy is the only source of unlimited energy, it has the potential to meet the needs of 10 billion human beings that we shall number in 2050. Therefore, renewable energy is a paramount solution for fighting the climate change. The potential of renewable energy is not only immense but also well distributed, unlike fossil fuels; let us not forget that 65 percent of oil is concentrated in the Middle East. Be it the sun, the wind, rivers, the sea, the heat of the earth, the forest and agricultural and industrial residues, each country on Earth has resources.

India is the founder-member of IRENA and it is the only country in the world to have a ministry dedicated to renewable energy and the potential is immense. Electricity from renewable energy already accounts for 9 percent of installed capacity. Globally, India is the 5th largest producer of wind energy; national champions, such as Suzlon, have been created and the resources are far from having been completely exploited. Today, exploiting the potential of solar energy – “Solar India” constitutes the next challenge.

Climate Change: Apprehension, Outlining & Mitigation


Change is the only constant in life. Though this philosophy is dated back to 500BC, still today its relevance hasn’t even decreased by a dime. Time changes, Tradition changes, Culture changes, Custom changes, People changes, their Priority changes, so does the Nature and its constituents. In fact, Change is so pervasive in human lives and livelihood that it almost defeats all descriptions and analysis in every possible way.

The world that we know today, it was neither the same some 1000 years back in past, nor will it be the same some 1000 years from now in future. It has incurred several significant changes in terms of its geology, demography, topography and climate too. Our planet’s climate has changed throughout the history. Sometimes it changes due to continental drift, sometimes it is the eruption of volcanoes that brings out the changes in climate. From the ocean currents to the comets and meteorites, reasons are a plenty for Climate Change, but today the world is collectively worried because these changes have been alarmingly speeded up due to many uncontrolled human activities.

The Buzz Associated

Climate change is already having several observable effects on our environment globally. The most significant among them is the steep rise of earth’s average temperature in recent times. The rise of 2o Fahrenheit in 20th Century might sound small in magnitude but, this actually is an unusual event in our planet’s history. The current global warming trend is of peculiar significance because most of it is sadly attributed to be the result of human activities since 1950s.

The anthropogenic activities have fast tracked the climate change on our planet. Heat waves, heavy rainfalls, floods and extreme weather conditions are occurring too frequently in many parts of the world. The trickle-down effects of climate change are adversely affecting the human health, agriculture, forestry and tourism in multiple ways.

The main cause of global warming or climate change per se is the human expansion of “Green-House” effect. Technically, the Green-House effect may be defined as absorbing of heat escaping from the earth’s atmosphere and radiating the same towards the surface of earth. The gases which contribute to green-house effect include – CO2, N2O, H2O, CH4 and CFCs (Chlorofluorocarbons).

On Earth, human activities are enhancing the natural greenhouse quite steeply. The industrial activities that our civilization heavily depends upon have raised the atmospheric levels of several greenhouse gases like CO2, methane and nitrous oxide manifolds.
