The polar regions are the two extreme regions of the Earth. It covers one-third of the world's area. It's like they're the end of the world. These are the hardest, coldest and windiest places to reach.

Winters at both poles are long, dark and freezing. Summers are short. The sun does not set for several months. During this short period of time, various animals come here to feed and have babies. These two regions are full of extraordinary natural beauties and are perhaps the last two untouched and clean regions of the world.

Climate change impacts on renewable energy supply

Abstract

Renewable energy resources, which depend on climate, may be susceptible to future climate change. Here we use climate and integrated assessment models to estimate this effect on key renewables. Future potential and costs are quantified across two warming scenarios for eight technologies: utility-scale and rooftop photovoltaic, concentrated solar power, onshore and offshore wind energy, first-generation and lignocellulosic bioenergy, and hydropower. The generated cost–supply curves are then used to estimate energy system impacts. In a baseline warming scenario, the largest impact is increased availability of bioenergy, though this depends on the strength of CO2 fertilization. Impacts on hydropower and wind energy are uncertain, with declines in some regions and increases in others, and impacts on solar power are minor. In a future mitigation scenario, these impacts are smaller, but the energy system response is similar to that in the baseline scenario given a larger reliance of the mitigation scenario on renewables.

Renewable energy could help lessen the worst possible impacts of climate change. Yet, the changing climate also impacts those very renewable energy sources. In a new study published in Nature Climate Change, researchers have estimated how global warming will impact the supply of eight key renewable technologies. The team does not present any sweepingly shocking results, and that precisely is the good news. If carbon emissions keep increasing until 2080, bioenergy supply could see a significant increase, researchers from the Netherlands Environmental Assessment Agency and Utrecht University found. The impacts on other renewables could be uncertain or detrimental, however. Hydropower and wind energy could decline in some regions and increase in others, while the potential of utility scale solar could decrease. Overall, though, the risks to renewable energy systems are modest, the study shows. Renewables today supply 15 percent of the world’s energy. Bioenergy forms the largest share of renewables at 10 percent, followed by hydropower at 3 percent, with solar, wind and others renewables making up 2 percent. By 2040, renewables might supply almost a third of the world’s energy, according to some models. Most renewables depend on climate processes, yet past studies looking at the impact of climate change on renewable energy supply “have focused on either a specific region or technology,” David Gernaat and his colleagues write in the paper. For a more comprehensive analysis, the team assessed the impact of two different warming scenarios on utility-scale and residential solar photovoltaics, concentrated solar power, onshore and offshore wind energy, bioenergy, and hydropower. They used general climate models to map, across the planet, climate parameters that directly influence renewables, such as the amount of solar power reaching the Earth, temperature, and wind speed. Further, by using temperature, carbon dioxide concentration, and precipitation, they calculated changes in sugarcane and corn yields as well as groundwater flows.

At the lower level of climate change in the first scenario, where emissions start decreasing in 2020 and go to net zero by 2100, the results for solar PV, wind energy and hydropower were all uncertain, “with no clear signal in either direction,” the researchers found.

The higher global warming scenario had a bigger impact on renewables, but results were mixed. The simulations find that the world’s tropical areas could have a small increase in solar PV and concentrated solar power, while there would be a considerable increase in potential in temperate regions such as the eastern United States, Europe and eastern China. Hydropower potential went down in Southern Europe and the southern parts of South America, Africa and Australia, and increased in Eastern Africa and India.

Across the world, the potential for concentrated solar and residential rooftop PV increased by 2 percent and hydropower potential increased by 6 percent. Bioeneergy potential worldwide, meanwhile, could jump by 32 percent. And utility-scale PV and wind energy potential went down. The impacts on hydropower and wind were especially strong on the regional scale.

This is one of the reasons behind the combined slow growth of temperatures, the melting of glaciers and the recent devastating eruptions in Australia.

Renewable energy systems play a critical role in combating climate change. Wind, solar, hydroelectric, and other renewable sources help mitigate climate change by reducing greenhouse gas emissions. Additionally, they minimize environmental impacts and provide economic benefits. With the widespread adoption and development of these systems, more effective progress can be made in combating climate change.

s a result of the industrialization process, humanity has had to face the problem of global climate change with the increase in the use of fossil fuels since the 1870s. This problem seriously affects almost all countries in the world, regardless of their level of development. Renewable energy or alternative energy sources have been advocated in recent years and stand out as the most agreed upon proposition regarding nature protection. With global warming, climate change and the decrease in limited natural resources, energy and production methods that do not harm nature and natural resources have become one of the priority demands of states, especially in the period following the signing of the Kyoto Protocol. In this study, the problem of global climate change and the importance of expanding the use of renewable energy resources for the management of this problem are revealed.

Climate change, which is a result of global warming, has brought about many environmental and vital problems. Many studies and projects have been produced in the arena of international climate change, which is accelerated by human factors and fossil fuel use. Additionally, many solutions have been developed in the context of combating and adapting to climate change. One of the proposed solutions for adaptation and struggle is to increase the production and use of renewable energy. In academic literature, it is not common to find generic models that combine climate parameters, solar energy potential and land cover evaluation.

When fossil fuels are used, they release gases we call greenhouse gases. When these gases are above natural levels, they cause the earth's atmosphere to warm up, causing global warming and therefore climate events that threaten the ecosystems of all living things, including humans.

With the rapid growth of the world population, the limited supply of non-renewable resources causes increasing energy demand, especially in developing countries. This situation causes the depletion of cheap fossil energy, increased environmental pollution and the risk of climate change. Therefore, researchers around the world are constantly trying to find solutions to diversify energy sources. As a result, renewable energy sources come to the fore. Oxford Dictionary (2000) defines renewable resources as natural energy that can be used again and again and will never run out.
