Many a heated discussion revolving around the topic: ‘Renewable Energy Resources’ have been conducted worldwide over the past so many years. But them one wonders how far have we succeeded in making use of such resources for producing energy. The Intergovernmental Panel on Climate Change (IPCC) seems to be highly optimistic on the note. IPCC says that renewable energy can power the world in 40 years. The report points out that the world can get 80% of its power from renewable sources by 2050 provided the governments and the related authorities take some ‘green policies’ for the cause.
Let’s go through some facts that the report highlights. Scientists are of the opinion that renewable energy will play a greater role than either nuclear or carbon capture and storage by 2050. It also exhorts us to increase the production of renewable energy by 20 times to tackle dangerous levels of global warming. However, the investment required to meet the greenhouse gas emissions targets is projected at $5trillion in the next decade, rising to $7 trillion from 2021 to 2030. Hardly around 1% of global GDP annually!
Unfortunately, the IPCC report suggests that wave and tidal power doesn’t seem to significantly contribute to global energy supply before 2020. But remarkably, statistics reveal that wind power contributed to 2% of global electricity demand in 2009 and is also expected to increase to more than 20% by 2050.
Though the IPCC report appears to be idealistic at the first instance, we have to admit that the proposals it envisages is inevitable for a ‘green future’.
