Climate Change and  the impact of  Energy System.

Climate Change and the impact of Energy System.

Climate Change is not merely a new name for us, it is one of the biggest hurdles that people are facing all over the whole world. We are witnessing many consequences of Climate Change. The scientists had predicted in the past about the climate change is now occurring, starting from the loss of ice-sheets, rise in the sea level, more intense heat waves,  problems of frequent wildfires, longer periods of drought, floods, and many more.

What is Climate Change and how Energy system is linked to it?

Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet regarding temperature, precipitation, and wind that are especially caused by human activities. As a result of unbalancing the weather of Earth, the sustainability of the planet’s ecosystems, the future of humans and the stability of the global economy is under threat. We can understand the seriousness of the climate change that the biggest crisis of the time, i.e.; global warming is one of the main aspects of Climate Change.

For the world leaders and people all around theworld, mitigating and adapting to climate change is the key challenge. At the core of these challenges is the question of energy — more precisely, our overall energy consumption and our dependence on fossil fuels. The global climate is changing and that is posing increasingly severe risks for ecosystems, human health and the economy. 

We know that the energy supply sector is the largest contributor to global greenhouse gas emissions. Globally, the use of energy represents by far the largest source of greenhouse gas emissions from human activities. About two-thirds of global greenhouse gas emissions are linked to burning fossil fuels for energy to be used for heating, electricity generation, transportation and industrial activities.

United Nations’ Report on Climate Change

Climate change is happening now, and we are not doing enough for it.  In fact, we are going backwards, according to a new multi-agency report from leading science organizations, United in Science released on 9th Sep. 2020, Climate Change has not stopped, Greenhouse gas concentrations in the atmosphere are at record levels and continue to increase. Emissions are heading in the direction of pre-pandemic levels following a temporary decline caused by the lockdown and the economic slowdown. The world is set to see its warmest five years on record – in a trend which is likely to continue – and is not on track to meet agreed targets to keep global temperature increase well below 2 °C or at 1.5 °C Global greenhouse gas emissions are linked to burning fossil fuels. Combustion of fossil fuels releases air pollutants that harm the environment and human health. Our use and production of energy have a massive impact on the climate and the converse is also increasingly true. We need to understand that climate change can alter our energy generation potential and energy needs. 

For example, changes to the water cycle have an impact on hydropower, and warmer temperatures increase the energy demand for cooling in the summer while decreasing the demand for heating in the winter. To succeed in limiting global warming, the world urgently needs to use energy efficiently while embracing clean energy sources to make things move, heat up and cool down.

Global  commitment to action

Global efforts so far to mitigate climate change culminated in the Paris Agreement in 2015. Through the agreement, 195 countries adopted the first-ever universal and legally binding, global climate deal. The target of the agreement — limiting the global average temperature rise to well below 2 °C, while aiming to limit the increase to 1.5 °C — is ambitious and cannot be achieved without a major overhaul of global energy production and consumption.

Share of Countries on CO2 emissions

According to the reports, China is the largest emitter of carbon dioxide in the world, according to the most recent data from the Global Carbon Project. But by the time second biggest contributor of greenhouse gases, the USA has pulled out himself from the agreement. Countries like  China and Russia are accused of not giving themselves ambitious targets. Some countries are doing well but we are sharing the same environment, one’s irresponsible behaviour affects the other.

How to fix it?

“No one is too small to make a difference” Greta Thunberg, one of the youngest climate change activist proved this and now it is time for everyone to acknowledge that it is not a responsibility of any one person or country. If we want to change, we have go bring change. And to avoid the worst impacts of climate change, we need to switch our needs toward renewable sources of energy as soon as possible, before the fossil fuel reserves are exhausted. The more we release greenhouse gases into the atmosphere, the less likely we are to limit the harmful effects of climate change. A good understanding of energy systems from existing research will provide multidimensional insights for appropriate actions against global warming. And COVID-19 came as a alarm for us, it has impeded our ability to monitor these changes through the global observing system.
