Wind energy and sustainable electricity generation: evidence from ...
The total electricity generated through the renewable energy sources was 244 terawatt-hours, which is under 40% of the total. Only 0.1 petawatt-hours or 21% of the aggregate electricity was produced from wind energy (British Petroleum, 2020 ). Hence, this has made the power sector to be a key source of the country''s emissions.
A Closer Look at the Environmental Impact of Solar and Wind Energy
The analysis shows that the HTP of the solar thermal plants ranges between 159 g 1.4‐ DCBeq/kWh and 192 g 1.4‐DCBeq/kWh, emissions 40% higher than those of the fossil fuel plants. This relatively high value is due to the NaNO 3 composition of the solar salts, which is higher for binary salts than HITEC technology.
The Downside to Renewable Energy
As ecological need and economic reality converge, renewables are going to make up an increasingly large percentage of the world''s power supply. It''s a necessary technological transition. But at the same time, renewables have a downside that needs to be addressed: rare earth elements. According to environmental attorney Christopher "Smitty ...

A Quantitative Renewable Energy Scenario for 2050. Figures 1 and and2 2 illustrate the Energy Committee''s global energy projection for the year 2050, compared to conditions in 2007. Figure 1 shows the shares of different renewable sources in the global primary energy supply, and Fig. 2 shows their share in the global production of electricity. …
Frontiers | A PESTEL and SWOT impact analysis on renewable energy ...
Similar to most developing countries, Togo continues to rely on the use of traditional forms of biomass energy which causes tremendous socio-economic, environmental, and health hazards. In addition, the imbalanced distribution and use of electricity, petroleum, and liquid gas reflect the disproportion in income and quality of life. …
A fresh look at nuclear energy | Science
The best energy sources which we should utilize for taming the global warming are solar radiation energy from outside the earth and magma energy from the interior of the earth (3). References: 1. John Parsons et al., A fresh look at nuclear energy, Science 11 Jan 2019: Vol. 363, Issue 6423, pp. 105 2.
Energy Sustainability with a Focus on Environmental Perspectives
A net-positive energy building over an average year generates more energy from renewable energy sources than it uses, as shown in Fig. 8, and can support energy sustainability (Rosen 2015; Endo et al. 2019; Delavar and Sahebi 2020; Tumminia et al. 2020; Singh and Das 2020). A net-positive energy building uses energy for a variety …
Climate and health benefits of increasing renewable energy …
the US in 2010 [5]. Deploying renewable energy (RE) generation is one of many strategies that can reduce reliance on fossil fuels, prevent emissions of GHGs, and reduce the health burden and other environmental impactsofelectricitygeneration [8–11].
