How Do They Work
True to their names, solar energy and wind energy generate electricity by using the sun and the wind, respectively. That is the easy way of describing the two of them. The way they actually work is a little more complicated than that.
To begin with, solar energy generates electricity either through the suns heat or the suns light. The former makes use of the Concentrated Solar Thermal systems , which concentrate the radiation of the sun to heat a liquid that will then be used to drive a heat engine and drive an electric generator. Meanwhile, solar energy can also produce electricity through light and the technology of Photovoltaic . Simply put, solar PV cells absorb light, which then knocks electrons loose. Then once those loose electrons flow, a current is created, which is then captured and transferred into wires, effectively generating direct electric current.
Wind energy, on the other hand, is actually another form of solar energy. It is caused by a combination of three concurrent events: 1) the sun unevenly heating the atmosphere, 2) irregularities of the earths surface and 3) the rotation of the earth. The way wind power works is that it uses wind turbines to convert the kinetic energy from the wind into mechanical power. And then, that mechanical power can be used for specific tasks like grinding grain or pumping water, or a generator can convert it into electricity.

How Many Solar Panels Are Needed To Power A House
The average household of four will need somewhere around 16 solar panels to supply all the energy a home needs. In other words, 4 solar panels per person within a household. However, this will vary depending on your daily usage of electricity, the average amount of sunshine you have daily, and the individual output of your solar panels.
Comparing Solar Vs Wind Energy
There are a number of important factors to consider when choosing a renewable energy plan. For example, youll want to start by comparing the energy efficiency and cost per watt of solar vs. wind energy. This will help ensure that both your energy costs and environmental impact are as minimal as possible.
Although wind energy is related to solar energy, it doesnt mean theyre the same across the board. Wind turbines have a larger generating capacity than solar panels, meaning theyre generally the more energy-efficient option. Additionally, the average cost of wind power was $0.06 per kWh in 2017, while the average price of solar energy that same year was $0.10 per kWh.
On the other hand, wind power is often generated in rural areas, making it costly to distribute to urban and suburban locations. So, unless you live near a wind farm, you may end up paying more than you would for solar.To ensure you make the best choice, you should always look at the details of your renewable energy plan and get an understanding of what youll be paying each month, as well as the impact your choices will have on the surrounding environment.

Can Solar And Wind Power The World
Renewables should be able to power the Earth one day. In fact, researchers have predicted that the planet could be 100% renewable by 2050 with solar and wind contributing to half of this energy. By that time, coal and gas will have been forced out by cheaper renewables.
Over the past few years, renewable energy has steadily risen in prominence offering a promising glimpse at a fossil fuel-free future. Currently, 40% of the UKs energy is sourced from renewables 20% from wind, 12% from biomass, and 6% from solar.
Can Solar Panels Or Wind Turbines Be Recycled After They Are Retired
Since the early 2000s when PV panels were first installed on homes, there really hasnt been a need to recycle them given their typically 25-year warranty. The need will become more pronounced in the next decade or two and theres every reason to believe that industry will meet the need. The same can be said about wind turbines.

Installing A Wind Turbine Vs Solar Panels
What You Need to Install Solar Energy
To install a solar system, youll need to have a large enough plot of land or a large enough roof to hold the panels. This area will also need to be exposed to sunlight for the majority of the day, unobstructed by shade from things like trees or buildings.
How much space do you need for a system? The more electricity you use and the larger percentage of that electricity usage youd like to cover, the more space youll need to install the solar system.
A home with a $120 electric bill each month would need about a 10 kilowatt solar system to cover their annual usage. This will take about 32 330-watt solar panels, which would cover 324 sq. ft.
If youre a business with an average electric bill of $600, youll need about 3,061 sq. ft. of space to hold your 157 330W solar panels. The good thing about solar energy is that panels can be placed on roofs, making use of underutilized space. Unlike wind turbines, solar energy systems dont create noise, and they can very safely be installed in close proximity buildings.
What You Need to Install Wind Power
Wind turbines may seem like the winner in this respect, as the mechanism itself takes up much less space. However, turbines need to be installed a good distance from any obstructions for safety reasons.

Pros And Cons Of Wind Energy
|Pros of Wind|
|Lessens the strain on the electric grid||The wind isnt constant|
|The fuel is free||Not cost-effective in less-windy locations|
Wind and solar share several of the same benefits. Like solar, wind energy generates no greenhouse gas emissions when producing electricity, thus reducing your carbon footprint. Wind also received federal assistance, and the wind itself has no price its totally free like the sun.
Theyre practically identical in every way. However, wind has one big advantage over solar in that it can create electricity at night. Wind doesnt stop when the sun goes down, but what you gain in nighttime generation, you lose in terms of consistency and location.
Currently, wind turbines are confined to areas like the West Texas plains wide-open spaces where wind can build up speed. If you build in a more populated area, you risk losing money because less-windy areas are not energy efficient.
Think of it like installing solar panels in the shade. Youll get some generation, but not as much as if you placed them in direct sun. Additionally, the wind doesnt blow all the time, and we can only predict the weather so much.
Finally, wind turbines can affect wildlife, like birds, bats, and other airborne creatures. However, the number of birds killed annually by cats 1.4 to 3.7 billion birds towers in comparison to deaths caused by turbines, around 140,000 to 500,000.3
Solar Vs Wind Energy: Which Is Best For A Homeowner
Ultimately, solar panels make the most sense because of the lower cost to install and maintain them.
Both methods offer clean, reasonably-priced alternatives to the escalating costs of fossil fuel energy, both financially and environmentally. Renewable energy allows you to be in charge of your own energy production and saves you money over the long term without generating pollution.
Future electric grids will have both wind and solar, but the role of wind will mainly be utility-scale, because installing and maintaining a wind turbine is not as financially practical as solar. For homeowners looking for a cost-effective renewable energy choice, solar panels remain the best option.

Future Outlook For Wind Energy And Solar Energy
Looking ahead for wind energy, the Global Wind Energy Council estimates that 435 gigawatts of new capacity will be added from 2021 to 2025. Government support will be a key driver, giving way to market-based growth.
“The world needs to be installing an average of 180 GW of new wind energy every year to limit global warming to well below 2°C above pre-industrial levels,” state the report’s authors, “and will need to install up to 280 GW annually from 2030 onwards to maintain a pathway compliant with meeting net zero by 2050.”
As for solar energy, the International Energy Association’s World Energy Outlook 2021 report pegs solar as now cheaper than coal. Along with wind energy, solar energy is expected to make up 80 percent of the global electric energy market by 2030. “Since 2016, global investment in the power sector has consistently been higher than in oil and gas supply,” explains the IEA report. “The faster that clean energy transitions proceed, the wider this gap becomes, and as a result electricity becomes the central arena for energy-related financial transactions.”
Lux Research predicts that the transition from fossil fuels to renewable energy sources will be accelerated by several years due to the impact COVID-19 is having on energy markets all over the world.
Wind Energy Can Be Produced All Night Long
Unlike solar energy, darkness doesnt affect how much power your wind turbine produces. This means that wind power is beneficial for locations in low-light areas or for homes that use a lot of power at night.
Solar energy can be saved up during the day to work at night, of course, but if you want to cut back on generators and batteries, wind energy can help with this as well.

Why Arerenewable Energy Sources Important
Asidefrom their many benefits, it is vital for people to phase out fossil fuels andmove into renewable energy sources for the bulk of their energy consumptionneeds. There are many reasons why this is the case:
- Fossil fuels will run out:Peak oil is swiftly approaching, and when it does, there will be bloody conflicts in the fight for natural resources if we dont have alternative forms of energy available for mass consumption.
- Fossil fuels are terrible for the environment: Coal-based power plants contribute many different pollutants to our environment, including sulphur dioxide , ground level ozone , and mercury .
- Renewable energy contributes to economic development: Each year, solar power and wind power industries contribute tens of thousands of jobs to the workforce, helping to maintain our economys stability while we continue to phase out older forms of energy.
- Energy security means national security: Any activity which contributes to the self-reliance of a nation makes that nation stronger, and more resourceful, so renewable energy isnt just advantageous to the individualits advantageous to everyone.
- Energy security means environmental security: Less dependence on fossil fuels such as coal and petroleum means less long-lasting damage to the global environment in the form of industrial accidents such as petroleum spills or habitat loss.
Windpower Vs Solar Power: Fire Safety
Firesafety is a big concern for homeowners when it comes to installing sources ofrenewable energy. It is also an area where solar power is more popular thanwind power when it comes to home setups.
While the fire hazards involved with solar panels are fairly low risk, wind turbines have an unfortunate reputation for catching fire due to their design constraints. This can make wind turbines a potentially dangerous addition to a suburban property, especially if it is close enough to a neighboring property for a flaming turbine to fall onto someone elses roof or yard.
Formaximum fire safety when installing either wind power or a solar panel on aresidential property, homeowners need to both have their setups inspectedregularly by a professional technician to ensure against electrical fires, andhomeowners need to have adequate fire escape plans in place should a fire breakout.
Solarpanels represent a relatively much lower risk of fire than wind turbines, but afaulty solar panel installed directly on a homes roof is a greater danger tothe residents than a wind turbine that catches fire in the yard. In eithercase, every precaution should be taken to prevent a fire.

Advantages Of Solar Energy Over Wind Power:
- Solar energy provides a more predictable energy output than wind energy. Energy production can be done in a massive scale with solar farms.
- Unlike wind turbines, Solar panels dont require particular space for installation as they can be installed on the roofs of houses or offices.
- Solar panels hardly produce any noise while wind turbines are noisy.
When Considering An Off Grid Or Grid Connect Power System The Two Main Options For Renewable Energy Equipment Narrow Down To Wind Turbines And Solar Panels So Which Is The Superior Clean Energy Source
Many people are searching for renewable energy sources in an effort to go green. Because we consume energy in such huge quantities, it only makes sense to look for a renewable, alternative, more environmentally-friendly ways to generate energy. Wind generator versus solar power is a common comparison: both forms of energy utilize natural, renewable energy sources, respectively from the wind and from the sun.
Both wind power and solar power have pros and cons. Its not too hard to find a sunny spot around a home to install solar panels. However, you cant generate wind! Wind turbines can only be used where you get sufficient wind. Wind turbines are sensitive to wind speed. Speeds that are too low will result in no power being generated from the turbine.
Solar panels generally consist of solar cells, which convert sunlight into energy we can use for solar home heating, solar water heating, and other uses. You may have seen residential homes covered with solar roof tiles to capture the suns rays. If you want to power your entire home or office building a large array of solar panels is usually necessary. The number of panels required varies depending on your location and energy needs.

How Does Wind Energy Work
Wind turbines generate electricity using similar principles as fossil fuel production, just using a different fuel source. If you look at the wind turbine, the electricity is being made at high altitude, right inside the cylinder shape behind the rotating blades. The wind pushes the blades into motion, which turns a shaft. This chain of motion eventually leads to a generator that makes electricity. The electricity then travels down the stem of the turbine and is taken to transmission lines to be transported and distributed to customers.
Innovation Could Change Which Energy Source Is More Efficient In The Future
As weve seen in the last few decades, the efficiency of renewables has improved dramatically. Solar panels, in particular, have become much better at capturing energy. Given that engineers are continuing to make improvements that increase efficiency, theres a good possibility in the near future solar panels will outperform wind turbines.
The other thing that could give solar energy the edge is the ability to install individual systems on homes. The vast majority of properties arent suitable for a residential wind turbine or its not allowed in the zoning, whereas many homes can accommodate a solar panel system.
The Pew Research Center notes that around 6% of homes have solar panel systems, but more homeowners are now seriously considering it. In 2016 40% of homeowners were considering solar power. Just three years later in 2019, that number was up to 46% of homeowners. Theres also been a 44% increase in the amount of solar power that was installed in 2019 and 2020. Those numbers suggest solar energy will continue to grow. As long as there is demand there will be innovation that improves the technology.
