As a world leader in carbon dioxide emissions, the U.S. is striving to make positive changes through policies and standards enacted through efforts like the Clean Power Plan. Due to this cumulative effect, even if we plan several generations ahead, the CO2 will still be in the atmosphere, making our planet warmer. Storms, nighttime, shade from trees or buildings, mean solar panels are not generating electricity 24/7. The study, conducted by climate change research scientist Aixue Hu of the National Center for Atmospheric Research and published Monday in the journal Nature … As such, global warming is not something we can stop tomorrow, and decisions made today about energy usage will have long-lasting impacts thousands of years into the future. However, advances in battery technology like the Tesla Powerwall are making battery-backed solar systems more of a reality. Meaning no carbon dioxide, sulfur dioxide or nitrogen oxide needed to generate electricity that would be harmful for the human’s health. However, emissions are released during the manufacturing, materials transportation, installation, maintenance, decommissioning and dismantling of the solar energy systems. According to a report from the National Renewable Energy Laboratory (NREL), utility-scale PV entails between one and five gallons consumed per MWh. What Are the Consequences If We Do Not Act to Stop Carbon Emissions? As technology improves in the renewable energy sector, efficiency rates increase and the cost per watt for installation will fall. Severe droughts, flooding, intense storms – everywhere you turn, the news is talking about extreme weather patterns that wreak havoc on the environment, economy, and society. In other words, once we extract them all, there will be no more electricity. The great advantage of solar panels is that they can be recycled, extracting mainly aluminum, glass and some minerals like silicon, copper, and polymers. Per capita, the U.S. releases 17 metric tons of CO2 emissions each year. The primary gas released into the air from burning fossil fuels is carbon dioxide (CO2). In June of 2019, the Environmental Protection Agency finalized the Affordable Clean Energy (ACE) Rule. During summer, when sunlight is strong, the deployment of solar panels can reduce the temperature by 0.2 K. However, despite their abundance, they are still exhaustible sources of energy. Some of the widely used renewable energy sources include … As solar energy keeps growing every year, these numbers have already surpassed the estimated values. "Giving more New Yorkers access to renewable energy can allow them to reduce their own energy bills while reducing stress on the grid and demand for fossil fuel power. Copyright © 2021 LetsGoSolar.com. Due to this ozone loss, the ozone layer depletes and leaves the ground wide open for ultraviolet radiation to reach our atmosphere. Seal and insulate your home. The Ozone Hole (Source – Union of Concerned Scientists in the USA). In order to better understand the impact of climate change on sea level rise (and therefore floods in coastal regions across the US) you can watch this amazing report from CNN that explains this further. Where your household’s energy comes from makes a big difference in how environmentally impactful a switch to solar can be. The sun is not always shining. With solar power, we can reduce our carbon footprint and much more. Mountaintop removal mining also releases large amounts of GHG emissions through clearcutting and burning of trees which can represent close to 7% of a coal power plant GHG emissions. However, besides its ideal position with respect to the Sun, there is an extra component that makes planet Earth unique in our galaxy: the existence of the ozone shield. The problem requires earnest, long-term responses. Climate change is a part of the human experience and will be for years to come. Coal is the third largest primary energy source in the U.S.; it’s also the dirtiest energy source. It’s difficult to predict how much consumers will be paying at the gas pump with numerous factors driving increases in cost. States like Wyoming on the other hand use coal as the principal emissions source. Therefore, scientists agree that there is no other natural source of explanation for this rapid increase in CO2 levels than human activity. Fossil fuel prices tend to fluctuate, sometimes wildly. This mineral reacts with water and air to form sulphuric acid and dissolved iron. Typical electricity emissions are 14,920 pounds per household annually. All of these contributions made by solar power plants are valuable in our fight against climate change, but what is climate change and how is it affecting our planet? Solar energy presents a set of advantages that can be used to offset carbon emissions and investing in solar for your house will also help your wallet. The U.S. Geological Survey estimates that on a national level, 41 percent of all freshwater withdrawals in 2015 were for thermoelectric power operations, primarily for cooling needs. This avoids the use of other older sources of light like kerosene lamps or candles in regions where there is no access to electricity, avoiding the risks of fire that can be harmful to the environment and for the communities. Either way, fossil fuels like oil will run out and nations will need to find alternative sources of energy. Fossil fuel power plants emit pollution into the air and water. On the other hand, the solar industry has focused on providing reliable quality standards to manufacture solar panels that incentivize the market to install PV systems at residential, commercial or utility-scale. Some regulations in the EU market known as the EU Waste Electrical and Electronic Equipment (WEEE), already require that manufacturers of solar panels finance the costs associated with collecting and recycling of expired modules. In a 2019 Gallup poll, only 22 percent of respondents said that the U.S. should place more emphasis on coal development with 50 percent saying there should be less emphasis. As one of the most commonly available, accessible, and feasible renewable energy options, solar panels are one of the main drivers in the reduction of carbon emissions across the globe. Pounds of CO2 emitted per million British thermal units of energy (Source – Energy Information Administration). When modules reach the end of their useful life, something must be done with the solar panel wastes. Your email address will not be published. This is energy derived from natural resources which cannot be depleted over time and can be replenished within a short period 9. Its effects can be seen everywhere across the globe. However, increasing the amount of GHG above normal values has a negative effect on Earth’s temperature because the layer becomes thicker than what it should be and heat increases radically, leading to high-temperature values with bad consequences for the planet. Fossil Fuels: The Core of the Climate Change Crisis "The entire world economy has grown up as a fossil fuels based economy and yet fossil fuels are at the core of the climate change crisis…We must undertake a kind of ‘heart transplant’ replacing the beating heart of fossil fuel energy with an alternative based on low-carbon energy!" Such solar panels can be connected to solar generators which allow the storage of power from the sun. The U.S. could generate much of its own electricity. Where there is sunlight and space, solar energy is accessible. This extra heat changes all facets of the world’s weather systems – from hurricanes to floods, a warmer world means more extreme, impactful weather. How cool is this? In fact, 10 other countries produce more carbon emissions per capita than the U.S. with Qatar generating an average of 44 metric tons of CO2 per person. Models for How Climate Affects Solar and Wind Power Potential. He notes that a few decades ago, climate scientists would project how the climate would look in a hundred years. Last updated: January 8, 2021. A comprehensive study conducted by NREL determined the total amount of greenhouse gases emitted over an energy source’s lifetime noted that: “While coal-powered technology used up 1050 g of carbon dioxide per kWh of electricity over its lifetime (a median estimate measured in CO2 eq/kwH), solar PV consumed 55 g CO2 eq/kWh.” The NREL researchers noted that for solar, as technology improves, its carbon footprint will see a downward trend. Reduces Air Pollution. Check out your state and see if your solar could do some extra carbon-offset good: We can figure this stuff out as long as we’re not lazy about it; as long as we don’t take the path of least resistance. Risks posed by solar mostly include threats to biodiversity. Solar power banks have also demonstrated to be more useful, safe and reliable under scenarios where the regular power grid is not available. As time is running out, the brightest minds in renewable energy are looking up. Massive oil spills and natural gas leaks can also wreak havoc on the environment. These variations are due to a number of factors: In Wyoming for example, the winter is cold with average low temperatures in January between 5 to 10 degrees Fahrenheit. For instance, the people from Portable Electric have designed a renewable power source solution for the off-grid sector called VOLTstack. Solar and other forms of renewable energy boast a very positive public opinion. Source – Global Status Report 2018 REN 21. This translates into 25 years where you do not need to worry about electricity generation and where no additional environmental damage will be done to continue the production of energy. Solar energy presents a set of advantages that can be used to offset carbon emissions and investing in solar for your house will also help your wallet. This translates into less burning and more materials that can be used for other purposes and mainly to the manufacturing of new or refurbished solar panels. Changes in the available amount of land and trees. This allows planet Earth to keep its temperature levels within ranges suitable for living, that would otherwise be too cold for the existence of life. There are also many health hazards caused by fossil fuels – contaminated water, land and air can lead to respiratory problems, cardiovascular issues and even cancer. The DOE notes that the U.S. emits 16 percent of global CO2 emissions, making it second in the world only to China, which contributes 28 percent of carbon dioxide emissions. Eight of the top 10 warmest years on record have occurred since 1998. Statistics and data provided by the International Atomic Energy Agency (IAEA). Reduce air leaks and stop drafts by using caulk, weather stripping, and … Then, when the rain comes, the compound transforms into diluted acid that falls into the streams and nearby rivers. When everyone joins forces to make lifestyle changes and environmentally conscious choices, humanity can become part of the solution instead of the source of the problem. Fossil fuels are sources of energy that exist because of decomposed plant or animal matter at high-pressure levels that accumulate underground over thousands of years. Actually, solar energy alone is enough as to provide the entire energy consumption of the world almost 100 times which could be supplied using only 1% of surface area from the Sahara desert. For instance, coal is generally extracted from the upper portion of the Earth’s crust in ore mines, recovering the coal from the mine using shovels and bulldozers to do the hard work. The air and water pollution emitted by coal and natural gas plants is linked … Moreover, other consequences of climate change are related to longer and harder droughts across the world, which also leads to less productive and less nutritious crops. ACE is an emission guideline that uses heat rate improvement (HRI) as the Best System of Emission Reduction (BSER) for CO2 from a coal-fired electric generating unit (EGU). The World Coal Association gives coal 150 years at current production rates. This can be translated into 18 million tonnes from coal sources, 3.38 million from natural gas, and 9 million from oil sources. While scientists like Dettinger cannot connect specific weather events to global warming, they predict that globally, storms will tend to intensify in magnitude, while a growing portion of Earth’s land mass will be forced to contend with increasingly severe droughts. Instead of depending on plugging in a campground site which electrical systems may not receive proper maintenance, it’s better to purchase solar panels for camping. When considering the future of the planet both for future generations to enjoy as well as the ability to sustain continued economic growth, renewable energy sources emerge as a logical response based not on short-term gain, but on principles that are both morally and economically sound. Recent studies from NASA on Greenland and the Arctic have demonstrated that continental-size ice formations are melting down due to the excess heat, and they have reduced nearly 10% in the last 30 years. To reduce the effect of this sector on carbon emissions, it is necessary to lower the energy intensity by enhancing vehicle and engine performance and substituting oil-based products by natural gas, bio-methane, biofuels or hydrogen. Thanks to its availability, battles over who controls or owns renewable resources (like sun and wind) are, at least for now, less likely – unlike with fossil fuels. Utilising it to generate power can greatly reduce the emissions of CO2 by decreasing the demand for fossil fuels. Renewable energy is one of the most effective tools we have in the fight against climate change, and there is every reason to believe it will succeed. For … According to the U.S. Energy Information Administration, current global oil supplies will only last until 2050. Portable solar panels can also contribute to the fight against climate change since every little drop of electricity that is not taken out of fossil fuels is good for the environment. Heating a home consumes a lot of energy, driving up emissions compared to other states. According to a report from the DOE, electricity disruptions cost the economy about $80 billion annually and endanger public safety and health. This generator, powered by solar panels, produces no contamination as a diesel generator would in environments such as forests, beaches, and deserts where carbon dioxide should not be emitted. These actions, while seemingly insignificant, can add up in big ways. Since solar energy is inexhaustible, there is no need to replace it with another resource in the future, assuring a safe and clean source of energy for the centuries to come. In fact, CO2 emissions per person can vary wildly by state. How can a computer scientist contribute to renewable energy or in general to reduce climate change effects? According to the report, if CO2 emissions are not cut 45% by 2030, then it will be unavoidable to reach 1.5°C increase in Earth temperature. However, if global temperature increases over 2°C, there may be no going back, and the effects of climate change would be unavoidable. According to NASA, since 1900 the temperature of the Earth has increased 1°C. However, when calculating the amount of water used to clean solar panels, the number comes out to 2/3 cup of water per megawatt-hour. China also made incredible contributions that reach 20 MT of CO2, and 25,000 GWh of energy injected to the grid. And it is not a surprise to jump to that conclusion when you take a look at CO2 emissions data from several countries. To get as much fuel out of the ground as possible steam, gasses, or chemicals are injected to oil flow more freely. If you’ve ever been to California, New … We can estimate the reductions in carbon emissions by using solar panels thanks to the IRENA calculator. PV panels do not require the use of water to generate electricity. With enough space, solar panels can be erected just about anywhere – on a parcel of land, carports, rooftops, the wings of a plane, cars and with advances in technology, they will even replace windowpanes. However, since the industrial revolution, carbon dioxide levels have increased to astronomic values close to 400 parts per million. One of the basic standards from any PV system is that the array will last at least 25 years. Clean energy: Clean energy is perhaps the biggest issue to tackle, but also the most important. Another way individuals can avoid carbon emissions is to use clean, renewable solar energy. When added together, we all contribute to climate change. For example, Wyoming produces nearly 104 metric tons of CO2 per person, while New York doesn’t even reach 10 metric tons. Dettinger notes that the sooner people can change to non-fossil fuel energy sources, the less CO2 will ultimately be in the atmosphere. There are thousands of planets in the universe, some with characteristics suitable for the existence of life and others so hot, so cold, or so toxic, that the existence of life as we know it may seem impossible. The world is turning more and more to renewable sources of energy – wind, solar power, and in some cases energy from flowing water – to fight climate change. Destruction of the ozone layer is also a secondary consequence of climate change. Considering just burning them down or throw them away into a pile of waste wouldn’t be exactly environmentally friendly, right? Stronger hurricanes, storms, snowfalls, hailstorms, and sandstorms can also be attributed to consequences of climate change that will intensify due to radical temperature changes. The Fourth National Climate Assessment Report from the U.S Global Change Research Program, released in November 2018, has announced an alarming top date to make a significant impact on carbon dioxide reductions.
