Renewable sources are renewable, sustainable, abundant and environmentally friendly. Unlike fossil fuels, they are not going to expire soon as they are constantly replenished. These countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind.

Advantages & Disadvantages of Alternative Fuels

Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world. Research efforts are aimed at addressing the challenges to greater use of wind energy.

This aerial view of a wind plant shows how a group of wind turbines can make electricity for the utility grid. The electricity is sent through transmission and distribution lines to homes, businesses, schools, and so on. Skip to main content. Advantages and Challenges of Wind Energy. Advantages of Wind Power. Wind power is cost-effective. Land-based utility-scale wind is one of the lowest-priced energy sources available today, costing 1—2 cents per kilowatt-hour after the production tax credit.

Because the electricity from wind farms is sold at a fixed price over a long period of time e. Wind creates jobs. The U. Wind enables U. The United States has a vast domestic resources and a highly-skilled workforce, and can compete globally in the clean energy economy. It's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas, which emit particulate matter, nitrogen oxides, and sulfur dioxide—causing human health problems and economic damages.

Wind turbines don't produce atmospheric emissions that cause acid rain, smog, or greenhouse gases. Wind is a domestic source of energy. The nation's wind supply is abundant and inexhaustible. Over the past 10 years, U. It's sustainable. Wind is actually a form of solar energy. Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. Wind turbines can be built on existing farms or ranches. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land.

Wind power plant owners make rent payments to the farmer or rancher for the use of the land, providing landowners with additional income. Challenges of Wind Power. Wind power must still compete with conventional generation sources on a cost basis.

Even though the cost of wind power has decreased dramatically in the past several decades, wind projects must be able to compete economically with the lowest-cost source of electricity, and some locations may not be windy enough to be cost competitive. Good land-based wind sites are often located in remote locations, far from cities where the electricity is needed. Transmission lines must be built to bring the electricity from the wind farm to the city.

However, building just a few already-proposed transmission lines could significantly reduce the costs of expanding wind energy. Wind resource development might not be the most profitable use of the land.

Turbines might cause noise and aesthetic pollution. Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape.

Wind plants can impact local wildlife. Birds have been killed by flying into spinning turbine blades. Bats have also been killed by turbine blades, and research is ongoing to develop and improve solutions to reduce the impact of wind turbines on these species. Like all energy sources, wind projects can alter the habitat on which they are built, which may alter the suitability of that habitat for certain species.

Pros and Cons of 10 Types of Energy

This article evaluates benefits and challenges of various energy sources, including solar, nuclear, wind, and more. Some energy sources are cleaner than others. However, all of them have an impact on the environment. You will be surprised to see that, during the manufacturing of parts, some green technologies may pollute and increase the greenhouse effect more than traditional energy sources. Technologies that are clean as they operate but have a great impact on the environment when they are manufactured especially regarding emission of potent greenhouse gases need more research before being widely adopted. In addition, a thorough analysis of what our planet will look like after the full adoption of these technologies is of utmost importance so future generations are not left in a deadlock. We invite you to share your research with the community by posting it online as a preprint.

Advantages and disadvantages of renewable energy

Solar panels can offset the energy used to make them in around four years. There are loads of awesome advantages of renewable energy - like the fact it will never run out! But it's also important to be aware of the downsides - for example, needing certain weather conditions to generate energy.

The conventional sources of energy, especially coal and oil are not only causing an irreparable damage to the environment but are also getting very expensive. Alternative energy offers a solution for the rising demand for energy but it is also posing a number of challenges. Environmental benefits. Low or zero carbon emission is without a doubt the main advantage of alternative energy over fossil fuels.

Alternative energy is defined as a resource that we use outside of what is possible from fossil fuels. That means items like wind, biomass, solar, and geothermal all qualify for this title. Hydropower is another option that fits into this category even though some producers need fossil fuels as a foundation to produce energy for consumption. The nature of what we look at as an alternative energy resource has changed in dramatic ways over time.

The news is rife with earnest chatter about climate change, "clean" or "renewable" energy, the environment and the need to rein in the burning of fossil fuels in order to stave off ecological and other crises in the coming decades. Despite this, the United States unquestionably remains an oil- and gasoline-powered economy for the most part as the second decade of the 21st century draws to a close. The advantages and disadvantages of alternative fuels are debated in the editorial pages of major newspapers in the United States and worldwide every day.

Local governments can dramatically reduce their carbon footprint by purchasing or directly generating electricity from clean, renewable sources. Using a combination of renewable energy options can help meet local government goals especially in some regions where availability and quality of renewable resources vary. Generating renewable energy on-site using a system or device at the location where the power is used e. Purchasing green power through through renewable energy certificates RECs - also known as green tags, green energy certificates, or tradable renewable certificates — that represent the technology and environmental attributes of electricity generated from renewable resources. Purchasing renewable energy from an electric utility through a green pricing or green marketing program, where buyers pay a small premium in exchange for electricity generated locally from green power resources.

Renewable energy sources are clean to use as there are fewer greenhouse gas emissions. The technology required is often expensive to purchase. Usually, the energy is produced at a slower rate than when using fossil fuels. Due to use of a stable source of energy, the cost of renewable fuels does not change much.
