Global warming is the gradual rise in earth’s surface temperature due to the effect of greenhouse gases released from burning fossil fuels and deforestation. Over the period of 1880-2012, the combined land-ocean temperature increased by 0.85° Celsius. Global average temperature is expected to rise between 1.4 – 5.8°C in the next 100 years.
A recent report by Intergovernmental Panel on Climate Change (IPCC) confirmed that human activities are ‘dominant cause’ of global warming since 1950s (IPCC, 2014).The climate change alters hydrological systems through precipitation change or melting of snow or ice and affects the quantity of available water, seasonal activities, and migration patterns.
In this post, I focus on global warming’s consequences in South Asian regions and the imminent need to collaborate to identify and reduce climate change related risks.
Serious Consequences of Global Warming
- Electricity supply and demand varies at different time intervals
- Electricity supply side is heavily based on renewable sources increasing the challenges of creating reliable electricity system
- Demand side management programs, storage systems, trade agreements with India can be some of the long-term solutions
Let’s start with few questions: What determines the supply and demand of electricity? Does the demand remain same throughout the year? What about the supply? Is it possible, technically and economically, to generate electricity as required to serve the load? These are few questions to consider before thinking about developing a reliable and adequate electric system.
In this post, I discuss issues that Nepal’s electricity sector may face in future. One of the previous posts discusses the short-term solutions of current power shortage problems. Moreover, the recent post talks about electricity sector’s possible issues in the future.
Nepal is facing severe power crisis at the moment. Even with the proper planning, it takes several years to develop necessary infrastructures for power generation and transmission. With Nepal’s never ending political turmoil, Nepal Government’s plans of reducing power shortages may take few more years than anticipated. Let’s explore some short-term plans of reducing power shortage. Besides increasing generation, are there any other ways to reduce power shortages in Nepal?
In the last post, I wrote if Nepal’s energy sector is focusing too much in hydropower. If we would like to diversify the energy mix, what are the potential resources at the grid-scale ? In this article, I briefly discuss run-off river hydro, pumped storage, fossil-fired generators, and wind and solar systems in Nepal’s context. If readers think that there are other potential energy sources, please feel free to mention them.
