The Use Of Renewable Energy Sources – Renewable energy is energy from resources that are renewable at all times but have limited availability such as hydropower, solar power, biomass power, geothermal power and wind power. Power is constantly expanding and never shrinking to keep it balanced. Renewable energy mainly provides power in four major sectors such as electricity generation, air and water heating or cooling, transport and rural electricity services.
Renewable energy sources such as solar energy, wind energy, hydroelectric power, and ocean energy are sustainable energy sources.
The Use Of Renewable Energy Sources
Renewable energy projects such as hydroelectricity or deforestation for biofuel production are not considered sustainable.

Skip to section What is Renewable Energy? Types of Energy Use Alternative Home Energy Products Wind turbines and solar panels in Palm Springs, California Vanja Terzic/iStock Renewable energy is growing rapidly, as innovation lowers costs and begins to fulfill the promise of a cleaner future. America’s solar and wind plants have broken records and are being fed into the national electricity grid without compromising reliability. This means that renewables are increasingly replacing “dry” fossil fuels, providing the benefits of lower carbon emissions and other emissions. But not all electronics marketed as “renewable” are good for the environment. Biomass and large lakes pose a difficult business given their impact on wildlife, climate change, and other issues. Here’s what you need to know about the different types of renewable energy – and how you can use this new technology in your home. What is Renewable Energy? Renewable energy, often called clean energy, comes from natural sources or renewable processes. For example, the sun and the wind are still bright and windy, although it depends on the time of day and the weather. Although renewable energy is often considered a new technology, harnessing natural energy has long been used for heating, transportation, lighting, and more. The wind moved the ship across the sea, the wind blew the corn. The sun warmed the day and helped keep the fire burning at night. But over the past 500 years, people have increasingly turned to cheap and dirty sources of energy, such as coal and fracking gas. Now that we have new and cheaper ways to capture and support wind and solar energy, renewables are becoming more important, accounting for more than 12 percent. of US energy production. Renewable energy also happens on a large and small scale, from large farms to solar panels, which can sell electricity back into the grid. Even entire rural communities (in Alaska, Kansas, and Missouri) rely on renewable energy for heating and lighting. As the use of renewable energy sources continues to grow, the ultimate goal is to improve America’s power grid, making it smarter, safer, and more integrated. All non-renewable, or “dry” energy includes fossil fuels such as oil, gas, and coal. Non-renewable energy sources are only available in limited quantities. When we pump gas from the station, we use distilled, unrefined crude oil that dates back to ancient times. Non-electric devices are also available in other parts of the world, making them more common in some countries than others. Instead, each country has access to solar and wind. Prioritizing renewable energy can improve national security by reducing the country’s dependence on imports from oil-rich countries. Many non-renewable energy sources can harm the environment or human health. For example, oil drilling may require open pit mining in the Canadian boreal forest; technologies related to fracking can cause earthquakes and water pollution; and coal-fired power plants pollute the air. In addition, all these activities contribute to global warming. Types of Solar Energy Humans have used solar energy for thousands of years – to grow crops, heat themselves and cook food. According to the National Renewable Energy Laboratory, “more energy from the sun hits the earth in one hour than all the people on earth use in a year.” Today, we use sunlight in many ways – to heat homes and businesses, heat water, and use electricity. Rooftop solar panels in East Austin, Texas Roschetzky/iStock Solar, or photovoltaic (PV), are cells made of silicon or other materials that convert sunlight into electricity. . Distributed solar energy produces local electricity for homes and businesses, from rooftop panels or community projects that provide power to the entire community. Solar farms can generate enough power for thousands of homes, using mirrors to reflect sunlight onto all the solar panels. Floating – or “floatovoltaic” – solar energy generation – can be successfully used in insensitive wastewater and water bodies. Solar power provides about 3 percent of America’s electricity generation (some sources estimate it will reach about 4 percent by 2022). But 46 percent of all new generation power will come from solar by 2021. Solar energy does not produce pollution or greenhouse gas emissions, and as long as they are responsible, most solar panels have an environmental impact outside of the manufacturing process. Wind power We are moving away from ancient wind turbines. Today, wind turbines as tall as buildings – with turbines of almost the same diameter – are gaining attention around the world. Wind energy turns turbine blades, feeds a generator and produces electricity. Wind, which accounts for 9.2 percent of U.S. electricity generation, has become one of the cheapest energy sources in the country. The top states for wind power include California, Iowa, Kansas, Oklahoma, and Texas, although wind turbines can be found anywhere with high wind speeds – such as mountains and open plains – or even out on open water. Other Electric Power Stations The electric power station is the largest electric power grid in the United States, although wind power is expected to grow rapidly. Electric power relies on water—usually fast-moving water in a large river or water flowing from an elevated surface—and converts that energy into electricity by turning the machine’s turbine blades. Nationally and internationally, large hydroelectric plants – or large dams – are often considered non-renewable energy sources. Large dams divert and reduce the flow of water, preventing access to animals and people living in the river. Small plants (with a capacity of less than 40 megawatts), controlled maintenance, less damage to the environment, because they change only a small part of the water flow. Biomass energy Biomass is organic matter from plants and animals, and includes plants, wood waste, and wood. When biomass is burned, chemical energy is released as heat and can produce electricity through a generator. Biomass is often misunderstood as a clean and renewable fuel and a green alternative to coal and other fossil fuels for electricity generation. However, research now shows that many types of biomass – especially from forests – produce more carbon than fossil fuels. It also has a negative impact on biodiversity. However, other types of biomass energy can be used as low carbon options depending on the situation. For example, sawdust and sawdust from sawmills that do not decompose quickly and emit carbon can be a source of low-carbon energy, energy from Geothermal Svartsengi thermal power station near Grindavík, Iceland Daniel Snaer Ragnarsson/iStock spring heat, use energy from geothermal. . . The Earth’s core is still as hot as the Sun’s surface, due to the low level of radioactivity in the Earth’s core. Drilling deep wells brings superheated underground water to the surface as thermal energy, which is then pumped through turbines to generate electricity. Geothermal generators tend to have low emissions when they release the gas and water they use back into the reservoir. There are many ways to build thermal plants without groundwater, but there are concerns that they could increase the risk of earthquakes in areas that are already considered hot spots. The power of ocean waves and tides is still in the development stage, but the ocean will always be determined by the moon’s gravity, which.

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.

Description : Energy is one of the main determinants of economic growth, but the high dependence of electricity production by fossil fuels could be a brake for the development of countries which do not have a sufficient level of richness and/or which possess a high level of environmental sensitivity. Countries tend to contrast these limits to growth using a higher percentage of renewable sources for electricity generation, though the technological limits still suffer. Renewable energy sources are appreciated worldwide for their ability to limit significantly the impact of anthropic activities on energy production and counter the gradual appreciation of the raw materials used in the process of traditional generation based on gas and/or oil power plants. Moreover, renewable generation can encourage off-grid generation in the underdeveloped countries.The attention to environmental issues has led several countries to ratify international agreements such as the Kyoto Protocol, Durban Protocol and, more recently, the Paris Agreement; these mandates pledge to reduce emissions of pollutants and to increase the share of energy produced through the use of renewable sources, but the results obtained so far are not encouraging.The relevance of the renewable energy generation and the increase in the investments in a newly installed capacity lead many scholars to investigate the relationship between economic growth and the key factors of the investments in RES. With this volume, the authors want to explore and analyze the causes and consequences of fragmentation and discussing policy responses on promoting renewable energy generation by shedding light on the policies proposed to promote the renewable generation and enhance energy efficiency, their effectiveness in reducing environmental degradation and the promotion of decarbonization, and discussing how developing countries do and should continue to invest in green generation....

Description : The United States and China are the world's top two energy consumers and, as of 2010, the two largest economies. Consequently, they have a decisive role to play in the world's clean energy future. Both countries are also motivated by related goals, namely diversified energy portfolios, job creation, energy security, and pollution reduction, making renewable energy development an important strategy with wide-ranging implications. Given the size of their energy markets, any substantial progress the two countries make in advancing use of renewable energy will provide global benefits, in terms of enhanced technological understanding, reduced costs through expanded deployment, and reduced greenhouse gas (GHG) emissions relative to conventional generation from fossil fuels. Within this context, the U.S. National Academies, in collaboration with the Chinese Academy of Sciences (CAS) and Chinese Academy of Engineering (CAE), reviewed renewable energy development and deployment in the two countries, to highlight prospects for collaboration across the research to deployment chain and to suggest strategies which would promote more rapid and economical attainment of renewable energy goals. Main findings and concerning renewable resource assessments, technology development, environmental impacts, market infrastructure, among others, are presented. Specific recommendations have been limited to those judged to be most likely to accelerate the pace of deployment, increase cost-competitiveness, or shape the future market for renewable energy. The recommendations presented here are also pragmatic and achievable....

Description : Climate change has become a major international issue and the British Government is committed to meeting ambitious targets for reducing greenhouse gas emissions within the present decade and beyond. Much of this will rely on an increasing use of renewable energy. Within current technology this will depend almost exclusively upon the use of rural land, whether for wind turbines, for growing biomass and biofuels or for the production of biogas. Renewable energy is therefore of immediate interest to farmers and landowners and to their advisers, such as surveyors, lawyers, accountants and bankers, as well as to planners and conservationists. This is one of very few books which addresses the issue of renewable energy from the point of view of landowners, farmers and rural land managers - those people who must make important decisions about how, where and when to install renewable energy sources on their land and the business implications of the decisions they make. The third edition of Renewable Energy in the Countryside contains a new chapter on biogas, up-to-date discussions on the implications of the Renewable Heat Initiative and new opportunities for solar energy and ground source heat in the context of farms and country houses as well as the implications of changes in UK planning policies....
