Climate change is haunting the very existence of the human race. Every year mercury is raising its bar, creating problems like food shortages, water scarcity and the extinction of many species to name a few. So many conferences have been held, so many pacts have been signed by the world leaders, but to no avail. The ghost of climate change still persists and it is imminent.
The ongoing dangers like that of climate change or global warming are the outcome of the gas emissions, greenhouse effect, deforestation and the burning of fossil fuel etc. We, the humans are the real culprits of it. Science has made so many leaps in the form of advancements and technology but still failed to eradicate these menaces completely. The burning issue of this era is the scarcity of water and lack of rain.
Water is one of the main sources of life and also the main element of producing energy globally. With that the other form of producing energy are fossil fuels or the conventional oil/gas. If we take the example of our country Pakistan, the main sources of producing energy are oil/gas and water.
Global warming has struck our country with full strength; it’s a catch-22 situation for us. Pakistan being an agriculture based country can never afford to bear such grave circumstances. Our country is already facing power shortages; energy crisis is the core issue needs to be solved soon before it poses more perils to our economy and lives. In this case, a concept of renewable energy can easily be implemented in Pakistan. Pakistan is endowed with so many blessings. The landscape, the ecology the climate here all favors the livelihood of the countrymen.
To cope with the running issue of climate change and its consequences like power shortage etc. renewable energy can be opted. Renewable or green energy comes from natural sources such as sunlight, wind, rain, tides, plants, algae and geothermal heat. These energy resources are renewable, meaning they're naturally replenished. In contrast, fossil fuels are a finite resource that take millions of years to develop and will continue to diminish with use. Renewable energy doesn’t overconsume the natural sources nor does it disturb the ecosystem. There are no or less hazards connected to the production of green energy as compared to the other methods of producing energy. The biggest chunk of capital is required at the time of installation of the equipment only. Whereas the total production cost of producing energy through conventional methods is always high.
India, which is next to us, was the first country to set up the ministry of non-conventional energy resources, in early 1980s. The total installed capacity of wind and solar energy is whopping 37,400 MW. The champion of renewable energy production is Germany.Roughly 27 percent of Germany's electricity is from renewables; the goal is at least 80 percent by 2050. On July 25, 2015, it was very windy in the north and sunny in the south. For a few hours renewables yielded about three-quarters of Germany's electricity.
China’s renewable energy sector is growing faster than its fossil fuels and nuclear power capacity. In 2015 China became the world's largest producer of photovoltaic power, at 43 GW installed capacity. China also led the world in the production and use of wind power and smart grid technologies, generating almost as much water, wind, and solar energy as all of France and Germany's power plants combined.
Even though China has the leading figures amongst all countries in the sector of renewable energy production, but its need are so colossal that in 2013 the water and solar energy catered only 20% of its power need.
There are certain challenges in relying completely on the green energy sources as of now. The sector is still in its nascent phase. There is a lack of understanding and skilled personnel in this sector. The cost of installing the equipment is too high. Masses still believe that it is a fancy way to produce power. There are some regions where there is no proper sunlight available and no wind channels for producing enough energy.
But the problem can be solved by using a mix of energy sources. In Pakistan the trend of producing power from renewable sources is taking pace now, many public and private sector companies are producing their own electricity. Government is also working hard to use the scorching heat of Southern Punjab and the heavy winds in Sindh to produce more energy out of green sources. The addition of Quaid e Azam solar park in this regards would reap its benefits in near future. Community awareness programs and social media engagement highlighting the role of green energy sources would definitely help. Degree programs related to renewable energy should be started in the Universities to produce more resource expert in this sector. Skill development programs would also help in producing the skilled labor for the renewable energy sector. FDI’s should be given lucrative propositions to invest in this sector.
Although it is challenging and difficult to use the true potential of the renewable sources available. But if serious steps will be taken by the countries that are already producing enough from this source and by installing the system in the countries where it is not yet implemented will bring a big change in the power sector. This will also minimize the coming dangers due climate change and global warming
