Negative Impacts Of Renewable Energy – The amount of renewable energy installed worldwide grew from 820 GW in 2006 to 2017 GW in 2016, growing at a constant rate of 8% per year and is expected to continue to grow. Several countries are increasingly announcing national and subnational policy instruments to increase the share of renewable energy.
India plans to triple its current renewable energy capacity from 59 GW to 175 GW by 2022 (approx.). Renewable energy is the choice of the future because it allows us to continue economic development without sacrificing the environment. However, while renewable energy appears to solve our growing energy needs and urgent need to mitigate climate change, the picture is far from straightforward. These projects continue to be contested by local residents and civil society organizations because they conflict with the local way of life and have a significant impact on the environment. Consider some of these implications in the Indian context.
Negative Impacts Of Renewable Energy
Large solar and wind farms require nearby land. Access to land is controversial, especially in developing countries like India. Renewable energy projects compete with local livelihoods, land conservation interests and other development activities.
Future Skills And Job Creation With Renewable Energy In India
A wind or solar project has a Plant Load Factor (PLF) of 18-20%. A thermal power plant has a PLF of 65-70%. Therefore, to produce the same amount of electricity as a thermal power plant, a solar or wind power plant would have to operate at three times the capacity. As a result, renewable energy projects require more land per MW than conventional energy sources. For example, a typical wind power project requires 15-20 hectares of land per MW. This complicates the picture, as many resource-rich areas for wind and hydroelectric projects are located in regions with high rainfall and biodiversity.
To implement renewable energy projects, it is necessary to cut down trees, install power lines and build substations to transfer electricity to the grid. Wind turbines are large structures that need to be transported to high altitudes and therefore have a significant impact on the local ecology. Engineers had to widen access roads, often creating debris on farmland, which in turn interferes with agriculture.
In areas with high rainfall, these changes can lead to soil erosion, conflicts with the livelihoods of local communities and severe soil erosion. Small hydroelectric dams are often considered large renewable and eco-friendly hydroelectric projects. However, altering river flow can affect water speed and depth, reduce river flow, and significantly reduce the quality of habitat for fish and aquatic life.
Karnataka has the greatest potential for small power projects with 4,141 MW and has utilized 29% of its capacity with an existing installation of 1,220.73 MW. Most of these projects are owned by private developers and are located in the ecologically diverse areas of the Western Ghats, which require deforestation and river diversion. For example, the 3 MW Bidalli Mini Hydel project in the Pushpagiri Conservation Area requires the construction of a dam, river tunnel, power well, power station and output line in the conservation area of the national park. The 24 MW Kukke power project at the confluence of the Kumaradhara and Gundia rivers is facing opposition from local communities as it threatens their traditional livelihoods and endangers the reserve forest.
Pros And Cons Of Nonrenewable Energy
In addition, the Ministry of Environment, Forestry and Climate Change exempted wind power projects of less than five hectares and small hydropower projects from mandatory Environmental Impact Assessment (EIA) requirements. EIA is an important indicator of environmental and wildlife damage in an area and is a major concern for conservationists. This poses a serious threat to the environment of the region where renewable energy projects are implemented.
In India, renewable energy projects require approval from panchayats. In most cases, certificates of approval for panchayats are given orally. Project promoters often use empty claims of providing electricity and economic benefits to poor rural communities to launch their projects.
There is no way to control the amount of electricity and how many homes will be supplied in the area. An example of this is the 113 MW Andhra Lake Wind Farm project on the edge of the Bhimashankar Wildlife Sanctuary in the Western Ghats of Maharashtra. Residents living near the project site are without electricity, despite the project putting their lives and the region’s diverse environment at risk.
Renewable energy projects pose a serious threat to biodiversity and lead to the destruction of land and life, but they are rarely criticized. Other possible solutions include empowering village panchayats and making EIA mandatory for all renewable energy projects. Also, providing electricity to people living near renewable projects will also help. Paying close attention to the social and environmental impacts of these projects will go a long way towards ensuring the equitable and fair development of renewable energy.

Description : Brings together disparate conversations about wildlife conservation and renewable energy, suggesting ways these two critical fields can work hand in hand. Renewable energy is often termed simply "green energy," but its effects on wildlife and other forms of biodiversity can be quite complex. While capturing renewable resources like wind, solar, and energy from biomass can require more land than fossil fuel production, potentially displacing wildlife habitat, renewable energy infrastructure can also create habitat and promote species health when thoughtfully implemented. The authors of Renewable Energy and Wildlife Conservation argue that in order to achieve a balanced plan for addressing these two crucially important sustainability issues, our actions at the nexus of these fields must be directed by current scientific information related to the ecological effects of renewable energy production. Synthesizing an extensive, rapidly growing base of research and insights from practitioners into a single, comprehensive resource, contributors to this volume • describe processes to generate renewable energy, focusing on the Big Four renewables—wind, bioenergy, solar energy, and hydroelectric power • review the documented effects of renewable energy production on wildlife and wildlife habitats • consider current and future policy directives, suggesting ways industrial-scale renewables production can be developed to minimize harm to wildlife populations • explain recent advances in renewable power technologies • identify urgent research needs at the intersection of renewables and wildlife conservation Relevant to policy makers and industry professionals—many of whom believe renewables are the best path forward as the world seeks to meet its expanding energy needs—and wildlife conservationists—many of whom are alarmed at the rate of renewables-related habitat conversion—this detailed book culminates with a chapter underscoring emerging opportunities in renewable energy ecology.
