The most obvious emblems of the drive for renewable electricity generation are wind turbines. Despite the fact that they use wind, which is as free and environmentally friendly as energy gets, the devices themselves are pure fossil fuels.
Large trucks transport steel and other raw materials to the construction site, earth-moving equipment clears a road to otherwise inaccessible high ground, and large cranes assemble the structures, all of which run on diesel fuel. The resources required for the production of cement, steel, and polymers are transported by freight trains and cargo ships. Steel alone accounts for 150 metric tons for reinforced concrete foundations, 250 metric tons for rotor hubs and nacelles (which house the gearbox and generator), and 500 metric tons for the towers in a 5-megawatt turbine.
How many tons of coal does a wind turbine require?
A meme misquotes a sentence from an essay written by scientist David Hughes, claiming that wind turbines will never yield as much energy as was required to build them.
The meme’s text goes as follows: “A two-megawatt windmill requires 260 tons of steel, 300 tons of iron ore, and 170 tons of coking coal, all of which are mined, transported, and manufactured using hydrocarbons. A windmill can spin till it breaks down, but it will never create as much energy as it took to build it. If you agree, “You’re an idiot if you support “The Green New Deal.” “I’m not sorry.”
Viewable examples of deceptive statements include (here), (here), and (here) ( here ).
The meme is based on a passage from ‘Climate Shift,’ a book of articles written by Thomas Homer-Dixon and Nick Garrison in 2009 concerning how Canada will adapt to climate change ( here ).
What is the number of solar panels required to equal a wind turbine?
You’re not alone in wanting to learn how to make the move to renewable energy sources for your home. More and more people are opting to transfer their homes’ electrical supply from fossil fuels to renewable energy sources. Not only is this good for the environment on a local and global scale, but it can also save you money.
What are alternative ways to power your home?
Fossil fuels face competition from a number of clean, renewable energy sources. Solar power, which uses photovoltaic panels to capture energy from sunlight, and wind power, which uses wind turbines to capture energy from the wind, are the two most common green energy choices.
What is the difference between solar energy and wind energy for home?
Solar energy and wind energy are both intermittent, and they function better in certain regions than others. Unless you live somewhere with drastically decreased light during the darkest times of the year, solar power can work at least in part all day, every day.
One of the most significant contrasts between solar and wind energy is that wind turbines require moving parts, but solar panels are permanently stationary.
What are the pros of solar energy?
- Year-round, sunlight can be found wherever you are (unless you live in an extreme environment)
- Any excess energy generated by your solar panels can be sold to utility companies.
What are the cons of solar energy?
- If you reside in an area where cloud cover is relatively consistent, this method will not be effective.
- The direction in which your solar panels are mounted has an impact on their performance.
- The energy that is not used immediately must be stored in batteries, which can be costly.
- Depending on how many you need to power your home, solar panels might take up a lot of room.
- Solar farms (and panels) aren’t particularly attractive, despite their proximity to the ground.
What are the cons of wind energy?
- Because wind is intermittent it may not always be fast enough to turn a turbine or may be too fast to utilize without causing harm to the turbine – you’ll need renewable energy from numerous sources.
- When using an unlimited renewable energy plan, the electrical generators inside a turbine are only designed to handle a certain amount of energy.
- If you decide to build your own turbine rather than adopt a clean energy plan, keep in mind that wind turbines require regular, very expensive maintenance due to the moving parts . and can only be carried out by a qualified professional
- Wind turbines can take up a lot of area, far away from any tall buildings or trees, and some people consider them to be a type of visual pollution because they must be so tall to collect wind energy.
- When built near a residence, wind turbines can have a harmful impact on bird populations because they may fly into them, and there is no way to prevent this.
Does wind or solar produce more energy?
So, now that we’ve looked at the benefits and drawbacks of both solar and wind energy, which provides the most energy for your home?
The ability of solar panels to convert sunlight into useful electricity determines their efficiency. Solar panels with the highest efficiency will be able to convert roughly 22% of the energy captured from sunshine into actual electrical energy, which doesn’t sound like much.
Wind turbines, on the other hand, may convert up to 60% of the energy captured from the wind into useful electricity. To put this in context, a single wind turbine produces the same amount of electricity as hundreds, if not thousands, of solar panels, but the size of the wind turbine will play a role.
Depending on where you are in the world, the answer to which will provide more energy will vary. Solar panels will provide significantly more energy than a single wind turbine at a sheltered but sunny area in California, even if the wind turbine is unable to generate energy on most days due to a lack of wind. Consider switching to a renewable energy plan that uses clean energy sources such as wind and solar to power your life.
Wind power produced 300 billion kilowatt-hours in the United States, whereas solar power produced 69 billion, so there’s a clear winner.
How many solar panels are needed to power a house?
To provide all of a home’s energy needs, a typical family of four will require roughly 16 solar panels. In other words, each household should have four solar panels. This, however, will vary depending on your daily electricity consumption, the average quantity of sunlight you receive each day, and the specific output of your solar panels.
How many solar panels does it take to equal a wind turbine?
A 5kW wind turbine will generate the same amount of energy per day as 24 solar panels, enough to power a home of six people. To generate this level of power, a large number of solar panels will be required, each of which must face directly towards the sun.
How much do solar panels cost?
Solar panels will cost between $11,000 and $15,000 on average, with a federal solar tax credit of 26% off the full amount. The type of solar panels you need, the quantity of panels you need, whether you want a rooftop or ground array, where you live, and who you pick to install your panels all influence the cost of installation. This works out to about $3.18 per watt on average. Some states, local governments, or utility companies may offer rebates or other incentives to help you save money on solar panel installation, and any local business should be aware of these opportunities.
How much does a wind turbine cost?
With Inspire, you may get wind electricity delivered right to your home with no installation fees. Switching to an unlimited renewable energy plan is simple and inexpensive, and it avoids the high expenditures of building your own wind turbine.
As previously stated, the average household will need a wind turbine that produces at least 5kW but no more than 15kW. With this in mind, the average cost of installing a wind turbine ranges from $15,000 to $75,000, depending on the size of the turbine, its height, and the equipment required, making switching a lot easier and less expensive. Over the course of a year, the average household wind turbine will generate between 8,000 and 12,000 kWh, resulting in an average cost of around $2 per kWh.
Is residential wind power cost-effective?
An unlimited energy subscription that never fluctuates is the most convenient method to immediately convert to clean and renewable energy for your house or company.
Can you combine solar and wind power?
The best choice is to use a renewable energy subscription from Inspire to combine solar and wind power and power your home with several renewable energy sources. This means you can use sustainable energy to power your home regardless of the weather or time of day.

Are wind turbines environmentally friendly?
Wind is a renewable source of electricity. In general, using wind to generate energy has less environmental consequences than many other energy sources. With few exceptions, wind turbines do not emit pollutants into the air or water, and they do not require water for cooling. Wind turbines may help lessen total air pollution and carbon dioxide emissions by reducing the quantity of power generated from fossil fuels.
The physical footprint of a single wind turbine is relatively tiny. Wind farms, or clusters of wind turbines, can be found on open land, on mountain ridges, or offshore in lakes or the ocean.
What are the negative effects of wind turbines on the environment?
Wind energy, like all energy sources, has the potential to harm the environment by reducing, fragmenting, or degrading habitat for wildlife, fish, and plants. Additionally, rotating turbine blades might endanger flying fauna such as birds and bats. Because of the potential for wind power to have a negative impact on wildlife, and because these difficulties could delay or prevent wind development in high-quality wind resource areas, impact reduction, siting, and permitting issues are among the wind industry’s top goals.
WETO supports in projects that strive to describe and understand the impact of wind on wildlife on land and offshore to address these concerns and encourage environmentally sustainable growth of wind power in the United States. Furthermore, through centralized information hubs like Tethys, WETO engages in operations to collect and disseminate scientifically rigorous peer-reviewed studies on environmental consequences. The office also invests in scientific research that allows for the development of cost-effective technology to reduce wildlife impacts at both onshore and offshore wind farms.
WETO strives to foster interagency collaboration on wind energy impacts and siting research in order to ensure that taxpayer monies are used wisely to solve environmental challenges associated with wind deployment in the United States.
- For more than 24 years, the office has supported peer-reviewed research, in part through collaborative relationships with the wind industry and environmental groups including the National Wind Coordinating Collaborative (NWCC) and the Bats and Wind Energy Cooperative.
- The NWCC was established in 1994 by the DOE’s wind office in collaboration with the National Renewable Energy Laboratory to investigate a wide range of issues related to wind energy development, such as transmission, power markets, and wildlife impacts. The NWCC’s focus has evolved over the last decade to addressing and disseminating high-quality information about environmental impacts and remedies.
- In May 2009, the Department of Energy’s wind office announced approximately $2 million in environmental research awards aimed at decreasing the hazards of wind power development to vital species and habitats. Researchers from Kansas State University and the NWCC’s Grassland Community Collaborative published a paper in 2013 that revealed wind development in Kansas had no significant impact on the population and reproduction of larger prairie chickens.
- The Bats and Wind Energy Cooperative has been involved in numerous research projects funded by DOE’s National Renewable Energy Laboratory since its inception in 2003, including studies evaluating the impact of changing the cut-in-speed of wind turbines (the minimum wind speed at which wind turbines begin producing power) and the use of ultrasonic acoustic deterrents to reduce bat impacts at wind turbines.
- Through a competitive funding opportunity, WETO is also financing research and development projects that increase the technical preparedness of bat impact mitigation and minimization solutions. Bat Conservation International, Frontier Wind, General Electric, Texas Christian University, and the University of Massachusetts are among the companies, universities, and organizations receiving funding from the Energy Department to field test and evaluate near-commercial bat impact mitigation technologies, which will provide regulators and wind facility owners-operators with viable and cost-effective tools to reduce bat impacts.

The Status and Findings of Developing Technologies for Bat Detection and Deterrence at Wind Facilities webinars hosted by the National Wind Coordinating Collaborative provide project updates and testing findings as of March 2018.
- WETO chose six teams in 2016 to work on improving solutions that will safeguard eagles that share airspace with wind turbines. For breakthrough, vital eagle-impact minimization technology research and development projects, more nearly $3 million was allocated across the six teams. The research financed by this grant will equip wind farm owners and operators with practical and cost-effective strategies for reducing potential eagle impacts. This important study expands on the Energy Department’s efforts to facilitate wind energy deployment while also ensuring animal coexistence by addressing siting and environmental concerns. If the study is successful, it will safeguard wildlife while also giving new tools for the wind industry to reduce regulatory and financial concerns.
- WETO is a supporter of research on biological interactions with offshore wind turbines. With this funding, researchers are gathering crucial data on marine life, offshore bird and bat behavior, and other factors that influence the deployment of offshore wind turbines in the United States. The Biodiversity Research Institute and a diverse group of collaborators, for example, completed the largest ecological study ever conducted in the Mid-Atlantic to produce a detailed picture of the environment in Mid-Atlantic Wind Energy Areas, which will aid permitting and environmental compliance for offshore wind projects.
WETO also collaborates with other federal agencies to create recommendations to help developers comply with statutory, regulatory, and administrative requirements for wildlife protection, national security, and public safety. The Wind Energy Technologies Office, for example, collaborated with the Department of the Interior on the Land-Based Wind Energy Guidelines and Eagle Conservation Plan Guidance.
A wind turbine can replace how many barrels of oil?
Offshore wind turbines may produce green energy, but they consume far more oil than their proponents disclose.
According to calculations released by Forbes on Wednesday, just laying the foundation for a single offshore turbine can require 18,857 barrels of marine petroleum during construction. Offshore wind farms frequently feature over 100 turbines, implying that only to power the ships involved in construction, about 2 million barrels of gasoline are required.
The Long Island-New York City Offshore Wind Collaborative will cost $1 billion to build and generate 200 megawatts of electricity, enough to power between 40,000 and 64,000 houses depending on the amount of wind that blows during the year.
According to calculations by the Daily Caller News Foundation, the wind farm’s power will cost about $25,000 each property it serves.
The first offshore wind farm in the United States will cost $17,600 per home it will power near Block Island, Rhode Island.
How many wind turbines would be required to replace one nuclear power plant?
It’s an ancient saying that a growing market can accommodate all players, including newcomers. The opposite is currently happening in the US power market, with more competition for static demand leading to headlines like this one from earlier this week: “Nuclear Plants’ Lifeline Threatens Wind and Solar Power.”
The United States is awash with energy, at least in terms of resources that can be converted into power.
The premise of that headline is paradoxical, given that renewables have relied on government mandates and incentives to drive their spectacular growth for more than a decade. They have made things more difficult for conventional generating technologies like coal and nuclear power, as well as lately cheap natural gas. In the case of coal, this was a foreseen and even purposeful effect, but in the case of nuclear power, it was largely unintended.
Inevitable fight
Much like the recession’s impact on gasoline demand produced a crisis for biofuel quotas, sluggish electricity demand has accelerated and deepened the inevitable battle for market share and the subsequent reorganization of generating capacity. Due to a poor economy and intensive energy efficiency efforts, US power consumption has been practically unchanged since the financial crisis of 2008-9. For all producers, more generation servicing the same demand equals lower pricing and fewer annual hours of operation for the least competitive.
At the same time, abundant, low-cost natural gas from booming shale production has made gas-fired turbines a direct rival in the 24/7 “baseload” segment once dominated by coal and nuclear power, as well as the go-to backup source for integrating additional renewables onto the grid.
Less nuclear power does not automatically imply more renewable energy. More gas or coal-fired power is also a possibility.
The United States is awash with energy, at least in terms of resources that can be converted into power. The sole remaining justification for the huge subsidies that wind and power continue to receiveover $3 billion budgeted for wind alone in 2017is environmental: primarily, concerns about climate change and the CO2 and other greenhouse gas emissions that are associated with it.
That’s why, in response to the recent wave of nuclear power plant retirements, some states are considering offering some type of financial assistance to existing plants. Nuclear power is not just the third-biggest source of electricity in the United States; it is also by far the largest producer of zero-emission energy, with 3.5 times the production of wind and 22 times that of solar in 2016. A significant reduction in nuclear power is just incompatible with the objective to reduce US emissions. Environmental organizations such as EDF have come to similar findings.
When it comes to determining what could replace nuclear, the scale of the reactor is even more important. For example, the annual energy production of a single conventional nuclear reactor is comparable to the output of nearly 2,000 wind turbines of 2 megawatts (MW) eachroughly half of the 8,203 MW of new US wind installations last year. An infographic I saw on Twitter helps me visualize this:
I understand why utilities and others who are actively investing in wind and solar power believe that providing incentives to keep nuclear power stations from retiring prematurely is “bad policy.” After all, we’ve pushed companies to invest in these specific technologies because it’s been easier to obtain an agreement at the federal and state levels to provide incentives for renewables than for all low-emission energy.
Even in states with deregulated power markets, we don’t have anything approximating an equal playing field for electricity generating.
But, as long as we’re supporting renewables in this way, we should acknowledge that nuclear power is just as valuable. The main advantage of renewables is their minimal emissions (including non-greenhouse air pollutants), which is something that nuclear power also has. However, because of their lower energy densities, which necessitate much larger footprints for the same output, and lower reliability, adding a lot more renewables to the energy mix necessitates additional investments in electricity grid modernization and energy storage, as well as new tools like “demand response.” Nuclear power is small and reliable, with a 90 percent availability rate. It also works well with the existing system.
