Solar Power vs. Wind Power Pros and Cons

Solar Power vs. Wind Power Pros and Cons

By Go Green In Your Home in How to Save Electricity

After doing some research on renewable energy systems or alternative energy systems as many will call them, I wanted to get the information out there as far as the advantages and disadvantages of the 2 main renewable energy systems, wind turbine generators and photovoltaic solar panels.

Both solar panel and wind generator systems are similar as far as how they are setup. You can have the wind generator grid tied or off grid, same as solar panels. Both the solar panel (photovoltaic panel) and wind generator will need a battery bank if you are using an off grid system. Both of these renewable energy systems will produce clean energy and help the environment as well as save you money in your home!

Advantages and Disadvantages of Wind Generator Systems and Solar Panel Systems

Now onto some of the advantages and disadvantages of each alternative energy system. None of this information is from my own personal experience as I do not have the financial funds to support the research. So the information about these renewable energy systems have came from researching the internet, talking to people that have these alternative energy systems, and of course some calculations of my own (prices, efficiency, etc.).

Wind Turbine Generator System Pros and Cons

The main advantage of wind generator is that they can produce electricity day or night as long as there is wind. Wind generators need less space on your land to produce sufficient electricity. Wind generators are able to produce more electric for the same price. If you spend $1,000.00 on wind generator you can produce 1kW – 2kW, with solar panels you may only produce around .5kW – .75kW with the same $1,000.00. Wind generators have moving parts, so there is always wear and tear on these moving parts. Bearings can go bad, propeller blades can be struck by objects, and heat may be generated. Your wind generator will be installed on a tower or pole of some sort to gain height where there is more wind, allowing lighting to possibly strike your wind generator. As wind hits the propeller blades there will be noise created, think of a fan and how they sound, or even taking a rope and swinging it fast in circles. You will get some of this noise from your wind generator. The propellers of the wind generator can also produce shadows flickering. Birds can get killed from flying into your wind generator’s propellers. There are vertical wind generators which will prevent this. So the quick break down of the wind generator system:

Report: Wind energy means billions to Illinois’ economy

Mon, 07/25/2016 – 1:21pm

NORMAL — A new report on the economic impact of wind energy in the state shows Illinois’ 25 existing wind farms have supported 20,173 jobs during construction and will add $6.4 billion to local economies over the 25-year life of the projects.

Released by Illinois State University’s Center for Renewable Energy, the report also shows how wind power creates jobs in the short and long term, provides millions of dollars for farmers and landowners, revenue for counties and municipalities, and supports businesses both in and out of the wind supply chain.

“Wind power does much more than generate clean energy,” said  Kevin Borgia, public policy manager for Wind on the Wires, a nonprofit organization based in St. Paul, Minn., that works to advance renewable energy in the Midwest. “Wind power is an economic engine for the state, providing jobs, landowner payments, tax dollars and business opportunities.”

The report further details all that the state’s wind farms offer, including $30.4 million in annual property taxes for local communities and $13.86 million in extra income for landowners who lease their land to developers.

America’s First Offshore Wind Farm Is Nearly Ready

  • The 30-megwawatt development to go into service in November
  • Europe has more than 10,000 megawatts of offshore wind

Deepwater Wind LLC is on the verge of completing the first offshore wind farm in U.S. waters, a milestone for an industry that has struggled for a more than decade to build in North America.

Workers have installed blades on four of the five 589-foot turbines at the site off the coast of Rhode Island and construction may be complete as early as this week, according to Chief Executive Officer Jeff Grybowski. The 30-megawatt, $300 million project is expected to begin commercial operation in early November.

“We will finish in advance of our original schedule,” Grybowski said in an interview at a dock on Block Island. “And we are in-line with our budget.”

After years of false starts, the offshore wind industry appears to be gaining momentum in the U.S. The federal government has awarded 11 leases to companies to develop projects along the East Coast, off New Jersey, Rhode Island, Massachusetts, Maryland and Virginia. This month, Massachusetts Governor Charlie Baker signed a bill requiring utilities to buy 1,600 megawatts of electricity from offshore wind farms over the next decade. And in the coming weeks, New York State plans to release a long-range plan to develop wind farms off the coast of Long Island.

The budget impasse is hurting Illinois when it comes to investing in renewable energy. This is getting ridiculous. Rauner’s quest to destroy public sector unions has got to stop. This lady spells it out in no uncertain terms.

Michelle Knox: Illinois must act now to fix its clean energy policies

Posted Apr. 19, 2016 at 10:05 PM

In 1970, more than 20 million people worldwide took part in the first Earth Day. Millions more will take part in Earth Day 2016.

As someone who delivers both wind and solar energy to customers in Central Illinois, I can attest to the need to fix Illinois’ energy policy — and quickly. I plan to be among those participating in a rally at the state Capitol in Springfield this week, during which we will deliver a strong message to Illinois leaders: by the time Earth Day 2017 arrives, it is critical that Illinois will have taken steps to reform our state’s out-of-date energy policies or we will lose clean energy jobs to other states.

Any day that goes by — let alone another year — without such a fix puts our state at risk of losing out on jobs and investments in this competitive field.

Fortunately, lawmakers have the chance to bolster our clean energy economy at the time we need it most. The Illinois Clean Jobs Bill (SB1485/ HB2607) would create more than 32,000 jobs and deliver more than $1.6 billion in savings to electricity consumers, while making vast improvements in public health. This bipartisan legislation would double the current standards for energy efficiency while increasing the targets for electricity generated by renewable energy sources, such as wind and solar, to 35 percent by 2030, up from the current target of 25 percent by 2025.

How Do We Fix It?

Germany Could Be a Model for How We’ll Get Power in the Future

The European nation’s energy revolution has made it a leader in replacing nukes and fossil fuels with wind and solar technology.

Published October 15, 2015

Hamburg knew the bombs were coming, and so the prisoners of war and forced laborers had just half a year to build the giant flak bunker. By July 1943 it was finished. A windowless cube of reinforced concrete, with seven-foot-thick walls and an even thicker roof, it towered like a medieval castle above a park near the Elbe River. The guns protruding from its four turrets would sweep Allied bombers from the sky, the Nazis promised, while tens of thousands of citizens sheltered safely behind its impenetrable walls.

Coming in at night from the North Sea just weeks after the bunker was finished, British bombers steered for the spire of St. Nikolai in the center of the city. They dropped clouds of metallic foil strips to throw off German radar and flak gunners. Targeting crowded residential neighborhoods, the bombers ignited an unquenchable firestorm that destroyed half of Hamburg and killed more than 34,000 people. Towering walls of fire created winds so strong that people were blown into the flames. Church bells clanged furiously.

The spire of St. Nikolai, which somehow survived, stands today as a mahnmal—a memorial reminding Germany of the hell brought by the Nazis. The flak bunker is another mahnmal. But now it has a new meaning: An urban development agency (IBA Hamburg) and the municipal utility (Hamburg Energie) have transformed it from a powerful reminder of Germany’s shameful past into a hopeful vision for the future.

First Offshore Wind Farm In The U.S. Kicks Off Construction

by Katie Valentine Posted on

Offshore wind is coming to the United States.

Construction on what will be the country’s first offshore wind farm started Monday in Rhode Island. The wind farm, which is being developed by Deepwater Wind, will be located off of the coast of Block Island, a small island about 13 miles south of Rhode Island. Once completed, the five-turbine, 30-megawatt wind farm will produce enough energy to power all homes and businesses on Block Island, which previously relied on diesel generators, according to the Sierra Club. The wind farm will also send energy to mainland Rhode Island. It’s expected to come online in fall 2016.

Environmental groups, many of which have pushed for the project since it started going through hearings in 2013, applauded the start of construction. Bruce Nilles, senior campaign director for the Sierra Club’s Beyond Coal Campaign, told ThinkProgress that the start of construction was a “landmark” moment for the U.S. wind industry, and that it “really makes real the promise offshore wind has” in the U.S., particularly on the East Coast.

 “This is technology that will play a very important part in decarbonizing electric sector,” he said.

This Island Will Charge Its Lake-Sized Batteries with Wind Power

This Island Will Charge Its Lake-Sized Batteries with Wind Power

Two hundred miles off the coast of Spain, a small island marked by a massive volcanic crater is about to become a case study for an ultramodern, zero impact society.

Over the last twelve years, engineers, researchers, and residents of El Heirro, the smallest of Spain’s Canary Islands, have been building one of the world’s most interesting living laboratories for sustainable off-grid living. They erected five towering wind turbines, built a huge reservoir that works as a battery, and installed three desalination plants that will let the tiny outpost harvest its drinking water from the sea. Now, the $75 million project is almost ready to be brought online.

The entire pioneering system is slated to begin its stab at modern closed-loop living at the end of June. While there are a number of solar power-reliant island communities, the press has dubbed El Hierro the first to live entirely off of the wind. Its only serious predecessor is Samso, a Danish island that’s also powered almost entirely by wind power, but unlike Hierro, it’s still wired up to the mainland’s coal-fired grid.

Right now, El Hierro relies on diesel generators to keep the lights on for its 10,000 residents, a practice that’s both costly and dirty. The new fleet of turbines will be capable of generating 11.5 megawatts of power.

That’s more than enough, when the gusts are ample, to keep electricity flowing to all of its homes and shops, as wells as to its three desalination plants. So when the gales are good, water and power are teased out of the sky—but it’s how El Hierro handles a lack of wind that harbors the biggest innovation.

Wind Farms Could Tame Hurricanes – That is a pretty radical conclusion

Posted on by

So a closer analysis leads to some doubts. First and foremost it takes “tens of thousands” of turbines to do it. That is A LOT of turbines. Second, the placement and the impact of that many turbines is not really considered nor what to do with the electricity generated. As the engineer said in the article building that many turbines is not feasible now. But it is a pretty exciting thought experiment.

http://www.usatoday.com/story/news/nation/2014/02/26/offshore-wind-farms-tame-hurricanes/5813425/

Offshore wind farms can tame hurricanes, study finds

Offshore wind farms can tame hurricanes rather than be destroyed by them, says ground-breaking research led by Stanford University that touts the benefits of wind power.

Billions of dollars in U.S. damage from mega-storms Katrina and Sandy might have been avoided with a perhaps surprising device — wind turbines.

That’s the finding of a ground-breaking study today that says mammoth offshore wind farms can tame hurricanes rather than be destroyed by them. It says a phalanx of tens of thousands of turbines can lower a hurricane’s wind speed up to 92 mph and reduce its storm surge up to 79%.

Unlike sea walls, which protect cities from storm surges, wind farms pay for themselves by generating pollution-free electricity, says lead author Mark Jacobson, an engineering professor at Stanford University. “The additional hurricane (protection) benefit is free.”

No offshore wind farms currently operate in the United States, although 11 are under development — mostly off the East and Texas coasts. Most of the world’s offshore turbines are in northwestern Europe, but China is ramping up its capacity.

Dong launches wind turbine demo project in Britain

LONDON (Reuters) – Dong Energy launched a project on Thursday to test two new giant offshore turbines at its wind farm off England’s Essex coast, marking a step forward in the next generation of wind turbine technology.

Energy minister Greg Barker opened the extension to Dong’s 172-megawatt (MW) Gunfleet Sands wind farm, off Clacton-on-Sea. The 6-MW turbines were supplied by Siemens.

The Department of Energy and Climate Change (DECC) said the turbines have the potential significantly to cut the cost of producing renewable energy from offshore wind.

The turbines will be tested to help Dong understand how the technology could be rolled out in future British projects.

Last year, Danish state-owned oil and gas group Dong agreed to buy 300 giant offshore wind turbines with a total capacity of 1,800 MW from Siemens for its British wind farms.

Petersburg school nominated for solar energy program

Dan Petrella 06/18/2013 – 11:22 PM EDT

PETERSBURG — The PORTA School District could soon add more solar power to its alternative energy portfolio.

Thanks to a wind turbine, solar panels and geothermal heating installed in 2009 at PORTA High School, the district has been saving about $350,000 a year in energy costs, School Superintendent Matt Brue said.

Now, a former student who works for Joule Solar Energy in New Orleans has nominated PORTA Central School for a program that aims to bring solar panels to schools through crowdfunding

Oakland, Calif.-based Mosaic offers an online platform for individuals to invest in solar projects.

When Bob O’Hara received an email from Mosaic saying that the company was looking for schools to work with, he thought of PORTA Central.

O’Hara, 29, attended PORTA schools through eighth grade before enrolling at Sacred Heart-Griffin High School in Springfield. He moved to New Orleans after graduating in 2002 to attend Tulane University, but he still visits his parents in Petersburg regularly.

He likes to check out the wind turbine at the high school on his visits and thought PORTA Central would be a good candidate for solar panels because of its long, south-facing roofline.

O’Hara said he also knows the district has been facing budget cuts due to dwindling state funding.

“One way to be able to invest in a school is to help them with their energy costs,” he said.
