Health & Environmental Benefits Of Solar Energy
Homeowners and utilities alike are choosing solar energy at a faster rate than ever before in the United States. The explosive growth of solar power is partly a result of the falling cost of solar panels. Rebates and incentives have also contributed to the United States biggest year ever for solar. But decreasing costs are only one of the many benefits of solar energy. You can also improve your health and protect the environment by reducing your reliance on fossil fuels and installing a solar energy system at your home or business.
Solar Power Conserves Water Resources
Water is one of the most essential natural resources on our planet. Moreso, clean water has become a scarce commodity.
For conventional electricity, water is an essential part of the manufacturing process. From extraction to transportation and power generation, manufacturers employ liters of water to produce energy. Although water used in power plants is returned, some evaporate or end up contaminated.
With solar, water conservation is possible. Solar panels need little or no water to produce electricity. This prevents hazardous chemicals and gases from polluting our water sources. It also preserves clean water.
Add An Electric Vehicle And Drive On Sunshine
Its pretty obvious that driving an electric car means fewer, if any, visits to the gas pump. Opting for an EV also means offsetting 100% of a traditional cars harmful C02 emissions. But what many people dont realize is that if you charge that EV from a non-solar home, all you’re doing is moving the energy expense from the gas pump to your monthly utility bill. A properly designed solar energy system will power your home AND your car while helping to further offset the dirty electricity that youd otherwise need to purchase from your utility.

Environmental Risks Of Mining
Most modern technology requires the use of rare minerals during the manufacturing process. Photovoltaic panels are no different and utilize more than 19 of these rare minerals. These are finite sources and are obsessively mined at various locations around the world. The demand for these minerals is extremely high, as countries strive to improve renewable energy production and meet consumers demand for technology.
Due to this massive demand, research shows that there wont be enough Indium to supply this green revolution. These findings are concerning, but even more so when you consider the impact of mining. It is proven that mining results in sinkholes, loss of biodiversity, and contamination of nearby water streams from highly acidic metal waste.
Solar Energy Reduces Respiratory And Cardio Health Issues
One of the biggest benefits of solar energy is that it results in very few air pollutants. An analysis by the National Renewable Energy Laboratory found that widespread solar adoption would significantly reduce nitrous oxides, sulfur dioxide, and particulate matter emissions, all of which can cause health problems. NREL found that, among other health benefits, solar power results in fewer cases of chronic bronchitis, respiratory and cardiovascular problems, and lost workdays related to health issues.
The benefits of solar energy are clear. Not only can you save money on your electric bills you can also reduce your carbon footprint and improve the health of those around you. Compare quotes today to see how much you can save by going solar.

Are Solar Panels As Green As You Think There Are Good And Bad Environmental Impacts Of Solar Power
Are solar panels really that green? The environmental impacts of solar panels are widely discussed and commented on but what arguments are valid, and what is social media noise?
Key arguments against solar panels are that they require more energy and fossil fuel-burning equipment to mine, manufacture, and transport than they save. Another argument is that toxic chemicals are used in the manufacturing process which do more harm than good.
Solar power isnt perfect
On the other side, it is argued that solar panels create more clean energy than they take to create and top global companies are truly leading by example with regards to chemical usage.
Here we will examine the positive and negative environmental impacts of solar panels and what the future has in store for the solar energy industry.
Greenhouse Gas Emissions Impact The Planet And Our Health
Scientists agree that extreme weather events are caused by an increase of greenhouse gas emissions, also known as GHGs, in the atmosphere.2 The U.S.s electric grid accounts for 28% of our GHG emissions, which is more than a quarter of the countrys total emissions.3
The environmental impact of greenhouse gases is undeniable, affecting weather, air quality, and health. Gases like carbon dioxide and methane hug the ground and trap heat that would otherwise continue rising to keep our planet cool.4 The human cost of toxic air pollution amounts to 60,000 American lives each year, due to illnesses related to heart disease, respiratory diseases, and even cancer.5

Energy Produced By Thermal Solar Panels
The amount of energy produced by solar thermal panels is usually defined on an annual basis . This can partly be justified by the fact that the limitation of energy production is not linked solely to the available sunlight but also to the objective in terms of quantity of water heated . From French regulations, for one person, the annual production with thermal solar panels is:
where T is the temperature difference between cold and hot water . The factor 1 2 comes from an adjustment to account for the fact that only a part of the need for warm water can be covered by solar energy. This factor can vary depending on location, climate , seasonality and technical features of the installation . A typical value of 1 2 is taken here. Furthermore, it is considered that this per capita energy requirement can be satisfied by 1 m2 of thermal panel. So, the power averaged over the year would be:
1 2 factor has disappeared here because we consider ideal heating conditions for the definition of the target. The production of the thermal panel is then computed in three steps:
2. The total amount of energy produced is summed from midnight the previous night to the current time t: tmidnightEther prod dt .
3. If the quantity of energy produced since midnight reaches the target Ether target, then any additional production during the same day is wasted and further energy production is set to zero.
To summarize, for solar thermal panels, the production is parameterized as:
Economic Impacts Of Solar Energy
Solar energy is one of the most promising renewable energy sources available. Not only is solar power clean and emissions-free, but its also abundant and increasingly affordable. The economic impacts of solar are already being felt around the world. Here are just a few examples: In 2016, solar generated nearly 1.3% of Americas electricity, enough to power more than 6 million homes. And according to the U.S. Department of Energy, that number is expected to grow to 20% by 2030. Solar is also having a big impact on jobs in the United States. There are now more than 260,000 solar jobs in the country, and that number is expected to increase to over 360,000 by 2020. Thats good news for workers and for the economy as a whole. And its not just the United States thats benefiting from the growth of solar energy. China has become the global leader in installed capacity, with over 77 gigawatts online as of 2016. And India is not far behind, with over 10 GW of installed capacity. These two countries are leading the way in making solar power a major force in the global energy mix. The benefits of solar energy are clear. Its time for governments and businesses around the world to embrace this clean, abundant, and affordable resource so we can all reap its many rewards.

Reduces Greenhouse Gases And Carbon Emissions
Most of the energy we use on the planet is produced from burning fossil fuels, which release carbon dioxide. This chemical compound generates heat once released into the atmosphere, thats why its called a greenhouse gas. Its said that carbon dioxide stays in the atmosphere for more than a thousand years, worsening global warming and negatively impacting the weather systems.
With solar panels meeting residential and commercial electrical needs, fossil fuels dont have to be burned to make appliances and other power-hungry devices work. Making your home more self-sufficient by mounting solar panels on your roof isnt only a way to reduce your electricity expenses but a planet-saving measure as well since it relies on a stable and renewable energy source.
What Do Solar Energy Do
Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.
What does solar power do for us? Solar energy creates clean, renewable energy from the sun and benefits the environment. Alternatives to fossil fuels reduce the carbon footprint at home and abroad, thereby reducing greenhouse gases globally. Solar is known to have a favorable impact on the environment.

Radiative Characteristics Of Solar Panels
To establish the energy balance of the equivalent urban canyon, the TEB model needs the albedo and the emissivity in the thermal infrared for the following main areas: road, roofs, facades, glazing. The French Center for Aerospace Research laboratory maintains a current database of optical properties of urban materials. Specific measurements were made for emerging materials: rough white paints, photovoltaic solar panels, metal cladding, and glass . The measurements for large samples of materials, e.g., for solar panels, were made using a goniometer .
Figure 2. Left: Goniometer used for albedo measurements. Right: Instrument used for emissivity measurements.
The measurement process is fully automated in the 0.42.5 m spectral domain. The position measurements acquired by the detector are regular in azimuth and zenith with an angular accuracy of 1°, except for the region of specular reflection, which is meshed more precisely.
The reflectance is measured with reference to a reflectance reference . Thereafter, the reflectance of the solar panel placed in the center of the goniometer is acquired for all recorded positions of the detector and the light source. The reference measurement is repeated at the end of the process.
The emissivity was measured using a SOC 400T apparatus . It measures the directional hemispheric reflectance for wavelengths between 2.5 and 20 m. The resulting emissivity was 0.93 for solar panels.
What Are The Pros And Cons Of Using Solar Energy For Your Home

Solar Panel Disposal And Recycling
When solar panels reach the end of their lifespan, we encounter another environmental concern: getting rid of the old panels. Solar panels are made of mostly recyclable materials around 70% of the panels can be reused. The 30% that cannot, however, can pose a threat to the environment if not disposed of properly. Panels might contain materials like gallium arsenide and cadmium-telluride that need to be disposed of or reused very carefully to prevent leaching and other environmental damage.
Leaving old solar panels in landfills would be not only toxic to the environment but also wasteful, considering the costly and often rare materials needed to make the solar cells. Unfortunately, there is no good widely used recycling system in place for solar panels as of yet. Recycling panels is expensive because there is a lot of time and effort required to do so.
With more panels around now than ever before, the issue of what to do with all the existing solar panels when they reach the end of their useful lives is a pressing one that has yet to be solved at scale.
What Is The Importance Of Solar Energy On Earth

Oil Spillage And Greenhouse Gas Emissions
Other issues arise when sourcing oil offshore or from the ocean. Manufacturers drill into the sea floor, which disturbs marine life and increases the risk of oil spillage.
As ocean tankers or pipelines transport oil through the seas and lands, accidental oil leaks and spills can occur, damaging our environment.
Power companies and utilities burn fossil fuels to make electricity, a process that releases toxic gases into the air. This contributes to massive amounts of greenhouse gases like carbon dioxide, which ultimately leads to environmental crises like global warming and climate change.
Because of the damaging effects of fossil fuels on the environment, many countries are switching to renewable energy sources like solar energy.
Simulation Configuration And Scenarios
We are now able to simulate the impact of the implantation of solar panels in a city on the UHI. The simulations are performed on the Paris metropolitan area, with TEB, coupled with the vegetation scheme ISBA for rural areas, within the SURFEX modeling software . The simulation domain is 100 km by 100 km, with a resolution of 1 km. At such a resolution, only the main characteristics of the buildings within the blocks in the grid mesh are kept. Geometric parameters are averaged in order to conserve the surface areas , while a majority rule applies for the architectural characteristics of buildings and the use to which they are put . These urban data are provided by a database at 250 m resolution , which contains block types as well as 60 urban indicators. Some parameters needed by TEB, such as albedos, thermal characteristics or equipment within buildings, are deduced for each 1-km-by-1-km grid mesh from urban block types and from the use and age of the majority of buildings. Countryside parameters, such as land use and vegetation characteristics are deduced from the ecoclimap database at 1 km resolution . The methodology presented in Masson et al. , based on a simplified Urban Boundary Layer generator is chosen, in order to be able to perform a simulation over an entire year. The chosen year of study is 2003, because it demonstrates the impact the solar panels would have during a heat wave.
