Coal 101 - What's Wrong with Coal?
Coal must be chemically cleaned and treated after mining. Fracked natural gas must be extracted using chemical mixtures. Both coal and gas are combusted to create electricity. Nuclear energy itself requires the handling of extremely radioactive materials. Solar panels have few components: a frame, cells, backsheet, protective film, conductors and a tempered glass cover. To make solar panels, the raw material must be mined, this is predominantly Quartz which is processed into silicon. Aluminum, and copper or silver are also key materials involved which must be mined, or obtained from recycled sources, but mostly they are mined due to the increased expansion of the PV industry in the last 10 years.
Following the mining of raw materials, the quartz is processed into electronic-grade silicon. This process involves heating the quartz in a high temperature furnace and reacting it with various chemicals. Other manufacturing processes are required for forming the extruded aluminum frame and rolling the tempered glass. Manufacturing anything generally requires vast amounts of energy. Solar panels take a lot of energy to create, but the total emissions are heavily front-loaded.
The manufacturing process is irrelevant without context of the lifetime generated energy as well as how other fuel sources stack up. Does the clean energy generated from solar panels offset the negative impacts during the mining and manufacturing process? Emission intensity is the lifetime total carbon emissions evaluated per unit of energy. The lower the emission intensity, the better the environmental impact, as less CO2 is emitted to generate the same amount of energy. These assessments included upstream, operational and downstream stages of energy generation from various fuel sources such as the solar PV, solar thermal, wind, nuclear, natural gas and coal. In , the U. The data was then harmonized using a discrete set of assumptions for comparison purposes. As one might expect fossil fuel-based energy generation methods produce more CO2 than renewable sources per kWh.
Coal produces 25x more carbon dioxide than solar energy to produce the same amount of energy. Even the worst estimates for solar PV is still 3x better than the best estimates for coal both situations being true is unlikely. The median and harmonized values paint a more accurate picture of the emission intensity of the fuel types accounting for statistical outliers. Emission intensity is an incredibly important metric that must be considered when evaluating the environmental impacts of solar power.
Other studies and meta-analysis have been conducted which confirm the environmental impacts of solar panels compared to other fuel sources found by NREL. If solar panels take more energy to create than they will produce over their lifetime, or similarly, if the upstream effects of solar panel manufacturing are worse than the operational benefits, the technology is fundamentally flawed. People often look at the return on investment ROI or payback period to gauge the value of a financial investment. How long will it be until I get my money back? This same question can be framed for energy generation and assessing the environmental impact of solar panels — how long will it be until the solar power system generates enough energy to offset the energy it took to produce?
The energy payback period for solar power depends on your location as different weather patterns affect solar generation. A solar panel installed in the Sahara Desert will produce more energy and payback much quicker than the same panel installed above the arctic circle. Once again, NREL provides some noteworthy data. This data includes manufacturing of the module, frame and balance of system components. With that in mind, it is reasonable to assume that solar panels have an approximate energy payback period of 1 to 2 years.
As the earlier figure suggests, generating solar energy instead of using coal-fired grid electricity will be far more advantageous than if you were installing solar panels to offset primarily hydro or wind electricity from the grid. Provinces such as Nova Scotia, Saskatchewan and Alberta would benefit from solar power the most since energy in these provinces come from primarily fossil fuels. Quebec stands to gain the least from solar power deployment as their grid is already nearly emission-free. Solar power is not perfect, but overall it provides a positive net environmental impact and financial impact.
These two irrefutable facts do not equate to solar panels having a net negative impact though, as the data suggests. The energy required to create a solar panel will be recouped in less than 2 years. Even considering the manufacturing and processing stage of solar, the emissions generated are 3x to 25x less than generating the same amount of energy from fossil fuels. The reduced emissions from using solarenergy versus any fossil fuel especially coal make the technology extremely beneficial. Questions, comments or concerns? We would love to hear your thoughts on this. There are good and bad environmental impacts of solar power Solar power is not without its downsides.
Chemicals, Recycling and Disposal of Solar Panels Recycling and disposal of solar panels is a key area of concern. Paths Forward Large scale solar panel recycling plants do exist, but are not as prevalent as they need to be. It takes time for secondary industries to develop around primary industries. All forms of electricity generation have an environmental impact on our air, water and land, but it varies. Producing and using electricity more efficiently reduces both the amount of fuel needed to generate electricity and the amount of greenhouse gases and other air pollution emitted as a result. Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted.
The chart below shows that most of the electricity in the United States is generated using fossil fuels such as coal and natural gas. A small but growing percentage is generated using renewable resources such as solar and wind. The emissions caused by electricity generation vary across the country due to many factors, including:. Use EPA's household carbon footprint calculator to estimate your household's annual emissions and find ways you can cut emissions. Use Power Profiler to generate a report about the environmental impacts of electricity generation in your area of the United States. All you need is your zip code. Power Profiler takes about five minutes to use. There are many ways to reduce the environmental impacts of your energy use.
