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
Last week, I got an opportunity to learn about Alaska Village Electric Cooperative (AVEC) during the annual conference of US Association of Energy Economics (USAEE) in Anchorage, Alaska. AVEC is a non-profit electric utility that provides stable electricity to 55 Alaskan villages with the help of distributed generation and local grid connection. There are similarities, in terms of geographic variations and dispersed population, between Alaskan villages and Nepal’s rural parts. AVEC has been successful in providing electricity to its villages, whereas most of the rural parts on Nepal are still deprived of electricity. In this situation, is there anything that Nepal can learn from AVEC? This post highlights the works of AVEC and the ways that Nepal can learn from them.
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.
