What does it mean to be committed to, powered by, or working towards 100% clean, renewable energy?
Committed to 100% Renewable Energy:
The Ready for 100 Campaign recognizes community commitments as places where a city’s leadership has established a goal to transition to the entire community to 100% clean, renewable energy. This can be through a stand-alone Resolution or Proclamation or integrated into a community’s Climate Action Plan or Energy Action Plan.
100% Commitment Guidelines
When crafting a commitment to 100% renewable energy, Ready For 100 recommends that the adopted goal includes the following elements:
- Community-wide Electricity Use: A full transition of the electricity sector to clean, renewable energy;
- By 2035: A target year for when this commitment will be achieved no later than 2035 for electricity and 2050 for all energy sectors;
Ensure Justice, Equity, Affordability, and Access: A commitment should include measures that prioritize equity affordability, and access for all members of the community, prioritizing low-income communities, environmental justice communities, and communities burdened by the fossil fuel industry. - Clean and Renewable Resources Only: This includes carbon and pollution-free energy sustainably collected from renewable sources including wind, solar, tidal, and geothermal. Low-impact, small hydro, and some forms of biomass may be included after being evaluated for sustainability and environmental justice implications. Nuclear, natural gas, coal, oil-based, or any other forms of carbon-based energy production are not included as clean or renewable sources of energy. Sierra Club’s complete energy policy can be found here.
- A Transparent and Inclusive Planning and Implementation Process ensuring that the community members and local businesses have an opportunity to participate.
Strong commitments also include:
- All Energy Sectors: A commitment to transition other energy sectors to 100% including transportation and heating and cooling;
- A Local Generation Goal: A goal for how much of the community’s energy needs will be met by local, distributed generation;
- Near term implementation steps: At least the first year and ideally a five year plan;
- Commitment to Collaboration: A commitment to work with surrounding communities in achieving aligned clean energy and equity goals;
- Commitment to Advocate: A commitment to advocate for policies or regulations at the state, regional and/or federal level that aid the city in their transition
Powered by 100% Renewable Energy:
A community is powered with 100% renewable energy when the amount of energy generated from renewable energy sources in the community (or brought into it) equals or exceeds 100% of the annual energy consumed within the community.
Working towards 100% Renewable Energy:
A number of communities have pledged support for 100% clean energy, and some are demonstrating support for a transition to 100% clean energy by investing in renewable energy for municipal operations. To see a list of cities that have invested in renewable energy for their municipal operations check out EPA’s Green Power Communities. To see a list of businesses, communities, and countries that are working towards 100% visit Go 100% Renewable Energy.

Biden’s tax plan shifting U.S. fossil fuel subsidies
Biden’s tax plan shifting U.S. fossil fuel subsidies
U.S. Treasury Secretary Janet Yellen on Wednesday released an outline of a tax hike proposal that would lower subsidies for fossil fuel companies while increasing incentives for clean energy in President Joe Biden’s infrastructure plan.
A Treasury Department office estimated that eliminating subsidies for fossil fuel companies would boost government tax receipts by more than $35 billion in the coming decade.
The “Made In America” tax plan did not specify specific tax breaks for fossil fuel companies that would be targeted. It said the historical subsidies undermine long-term energy independence and align with factors creating climate change
One of the top fossil fuel breaks is called intangible drilling costs, which allows producers to deduct most costs from drilling new wells. The Joint Committee on Taxation, a nonpartisan congressional panel, has estimated that ditching it could generate $13 billion over 10 years.
The Biden tax plan would advance clean electricity production by providing a 10-year extension of the production tax credit and investment tax credit for clean energy generation, such as wind and solar power, and energy storage. It will also create a tax incentive for long-distance transmission lines used to create an eco-friendly smart grid across the United States.
The plan would restore a tax on polluters to pay for Environmental Protection Agency costs associated with Superfund toxic waste sites, addressing the harm caused by fossil fuel production.
Greenpeace, an environmental group, said the plan does not go far enough, citing a study here calculating that U.S. fossil fuel companies get $62 billion a year in implicit subsidies for not having to pay for the damage their products do to the climate and human health.

Solar Panel Care and Maintenance Tips
The following four tips are all you need to know about solar panel care and cleaning.
One of the big advantages of solar energy systems is the fact that they require so little care or maintenance. With no moving parts, solar installations undergo very little degradation over time. Engineering.com reports that the life expectancy of solar panels has increased in recent years as the manufacturing process and technology have become more sophisticated. The old rule of thumb used to be that panels would lose 1 percent of their effectiveness with each passing year, but that figure has now substantially decreased to half a percent. Now that solar panels are being made with monocrystalline silicon, they will maintain 92 percent of their efficiency after 20 years.
Inspect Your Solar Panels Regularly
For the most part, solar panels are placed in locations where they are not vulnerable to ground-level damage. However, it’s a good practice to give your panels a close-up inspection from time to time, in order to make sure you’re not losing power due to a buildup of pollen or tree material. The same type of dirt that accumulates on your windows will eventually find its way to your solar panels, so it makes sense to check their cleanliness now and then. Also, in rare instances, solar panels have been known to suffer damage due to extreme hail storms.
Clean and Care for Your Solar Panels
In most cases, rain and weather will take care of keeping your panels clean. This is especially true when solar panels are installed at a steeper tilt, because dust and pollen will typically be washed off with every rainfall. If your panels do happen to acquire an unusually heavy coating of dust or pollen, however, you can easily clean them with plain water and a little mild dish soap or you can just direct the hose spray up to their panels and shower them off, imitating the action of rain.
The main thing to watch out for is any danger of scratching the glass because this can reduce the light that gets to the solar cells. For this reason, when you choose solar panel cleaning products, it’s important to avoid any type of abrasive cleanser. Detergent cleansers can also be problematic because they can leave streaks and smudges that may be hard for you to see. These can also decrease the light that passes through. Rubbing alcohol dissolved in water can take care of any oily residue or other dirt that may have found its way onto the glass. If you’re going to wipe down your panels, you should generally use a soft cloth or squeegee. Since solar panels are made of glass, you don’t need to shop for specialized solar panel care or cleaning tools.
Sun and Shade Monitoring
To maintain maximum effectiveness, your solar panels have to be in the sun for as many hours as possible. When they are installed, they will be placed in a location that gets maximum sun exposure. However, trees can grow over the years and the patterns of sun and shade can change. New construction on adjacent lots may also have an effect on how much sun your installation gets. Because of this, during the lifetime of your panels, it’s important to make sure that they are still located with the best possible sunlight orientation.
Checking Energy Usage
You may not feel that you need to check your own energy usage, since your net metering arrangement with the local utility company will show you how much energy you’re selling back to the grid. The downfall of relying solely on their numbers, however, is that you’re not directly measuring the energy output of your panels. Installing an energy monitor is your most direct way to make sure your entire system is performing correctly.
All of our solar systems allow you to monitor your energy usage. Inverters show your immediate power output as well as some daily and cumulative data.
If you love apps, rest assured that many monitoring devices would provide you with remote data, so you can pick up your phone and check on how your panels are doing at any moment. Various information-gathering and analytic operations can be performed by dedicated data-logging hardware that can be connected to your inverter. These devices may perform the operations internally, or they may send the information to your computer and use its software to provide you with useful charts and logs. The more complex levels of data tracking are certainly not a requirement for maintaining your home solar installation, but many new solar panel owners are fascinated by observing the performance of their systems.
Solar, wind expanding rapidly in US market
Solar, wind expanding rapidly in US market
The Solar industry’s growth has accounted for nearly 3.4% of the total US generation thus far this year, with wind contributing 8.5%. Coal, meanwhile, has plunged from about 30% last year to just 17.8%.
2020 has witnessed strong growth of renewable generation and rapid declines in fossil-fuel production and consumption, the U.S. Energy Information Administration’s (EIA) Electric Power Monthly report states that solar and wind are the fastest-growing sources of U.S. electricity.
This summer, solar, accounted for 3.5% of the nation’s total energy generation, up nearly 20% from 2.8% in July 2019. In the January-July 2020 period, solar accounted for nearly 3.4% of the country’s generation, up 22.1% from the 2019 year-to-date mark of 2.6%.
All renewable energy sources are taken into account, clean energy made up 9.5% of all electricity generation in July and renewables with hydroelectric provided 21.2% of total electrical output, up from 19.2% a year ago.
The 2020 highpoint happened in May, where renewable resources reached an all-time peak contribution of the country’s electricity generation at 25.3%. These gains have been driven by the growth of wind and solar.

Solar Industry Sets Records in 2020
Solar Industry Sets Records in 2020, On Track to Quadruple by 2030
Tuesday, Mar 16 2021
WASHINGTON, D.C. and HOUSTON, TX — The U.S. solar industry grew 43% and installed a record 19.2 gigawatts (GWdc) of capacity in 2020, according to the U.S. Solar Market Insight 2020 Year-in-Review report, released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie.
For the second year in a row, solar led all technologies in new electric-generating capacity added, accounting for 43%. According to Wood Mackenzie’s 10-year forecast, the U.S. solar industry will install a cumulative 324 GWdc of new capacity to reach a total of 419 GWdc over the next decade.
“After a slowdown in Q2 due to the pandemic, the solar industry innovated and came roaring back to continue our trajectory as America’s leading source of new energy,” said SEIA president and CEO Abigail Ross Hopper. “The forecast shows that by 2030, the equivalent of one in eight American homes will have solar, but we still have a long way to go if we want to reach our goals in the Solar+ Decade. This report makes it clear that smart policies work. The action we take now will determine the pace of our growth and whether we use solar to fuel our economy and meet this climate moment.”
The 8 GWdc of new installations in Q4 2020 marks the largest quarter in U.S. solar history. For perspective, the U.S. solar market added 7.5 GWdc of new capacity in all of 2015. New capacity additions in 2020 represent a 43% increase from 2019 and breaks the U.S. solar market’s previous record of 15.1 GWdc set in 2016.
This is the first time Wood Mackenzie has released a long-term forecast as part of the U.S. Solar Market Insight report series. By 2030, Wood Mackenzie is forecasting that the total operating solar fleet will more than quadruple.
“The recent two-year extension of the investment tax credit (ITC) will drive greater solar adoption through 2025,” said Michelle Davis, senior analyst from Wood Mackenzie. “Compelling economics for distributed and utility-scale solar along with decarbonization commitments from numerous stakeholders will result in a landmark installation rate of over 50 GWdc by the end of the decade.”
California, Texas and Florida are the top three states for annual solar capacity additions for the second straight year, and Virginia joins them as a fourth state installing over 1 GWdc of solar PV. In 2020, 27 states installed over 100 MWdc of new solar capacity, a new record.
Key Figures:
- Residential deployment was up 11% from 2019, reaching a record 3.1 GW. This was lower than the 18% annual growth in 2019, as residential installations were significantly impacted by the pandemic in the first half of 2020.
- Non-residential installations declined 4% from 2019, with 2 GW installed. The pandemic impacted this segment through delayed project interconnections and prolonged development timelines.
- There was a historic 6.3 GWdc of utility-scale projects installed in Q4 2020, bringing the annual total just shy of 14 GWdc.
- A total of 5 GWdc of new utility solar power purchase agreements were announced in Q4 2020, bringing the volume of project announcements in 2020 to 30.6 GWdc and the full utility-scale contracted pipeline to 69 GWdc.
- The 2-year extension of the ITC in the final days of 2020 has led to a 17% increase in deployment in our 2021 – 2025 forecast.
The Future Of Clean Energy: Self-Healing Solar Panels
A material used commonly in solar panels has been seen to repair itself when damaged, and scientists think this ability may be critical for the future of clean energy.
The substance, called antimony selenide (Sb2Se3) aka the solar absorbing material that can be used to turn light into electricity. The findings from the University of York, UK raise the possibility that it may be possible to create long-lasting solar panels. According to the research team, the panels could not only self-heal when damaged but also reduce costs and improve scalability.
Currently, solar panels have an average lifespan of between 25 and 35 years. The new technology of self-healing substance, could be a critical breakthrough. Professor Keith McKenna, who led the research, explains antimony selenide’s self-healing capability is analogous to a starfish or reptile that can regrow a limb after an accident. He adds that antimony selenide can repair broken bonds created when it is cleaved by forming new ones. Plus, the ability is as unusual in the materials world as it is in the animal kingdom and has important implications for applications of these materials in optoelectronics and photochemistry.
The adoption of Solar power is growing around the world at an unprecedented speed and many governments are pledging to reach net-zero over the next 10 to 30 years, and securing reliable alternatives to fossil fuels seems critical.
Researchers at GlobalData believe that space-based solar power (SBSP) may be the key to a total transition to green energy. SBSP works on using mirror-like reflectors, which are placed on satellites that move around Earth’s orbit. The reflectors would concentrate the sun’s energy onto solar panels, and allow for power to be harnessed outside of daylight hours. At the moment, solar panels collect power for an average of 29% of the day, but SBSP would mean they could be illuminated 99% of the time.
For now, SBSP is conceptual, and scientists believe it could be a reality soon. The US Naval Research Laboratory conducted its first test in this field in May 2020. Earlier this year, scientists in South Korea created the first fully transparent solar panel, which is said to be a major step forward for domestic solar power usage. Traditionally, they are opaque because of the semiconductor layers within the cells, but the research team at Incheon University could use titanium dioxide and nickel oxide instead. In 2020, double-sided solar panels were developed for the first time, which were 35% more effective.
Maintenance Tips for Solar Panels
Maintenance Tips for Solar Panels
If you have solar panels on your home, you have made a good decision. Not only are you saving on energy costs every year, but you have very little upkeep to worry about! Solar panels are very easy to care for. The front of a solar panel made out of tempered glass and will hold up well in tough conditions. . Outside of an occasional wash, you don’t really have anything to worry about.
Don’t worry about cleaning if it rains regularly where you live. If it rains where you live , you really don’t need to clean your panels. The rainwater will be enough to wash away any dust or debris from your solar panels. It’s not recommended to use strong soap on your solar panels anyway, so it’s usually unnecessary to get up there and scrub the panels manually.
- Solar panels are made out of tempered glass, which tends to be pretty resilient. Still, it’s best to take a quick look from the ground after any hail storms or thunderstorms to look for cracks. If you ever have a cracked panel, contact the installation company to have it repaired. Solar panels are typically covered by warranty for 10-25 years.
- To make a long story short, you probably aren’t losing that much power even if the panels are filthy. One study found that solar panels produce 96-98% of the energy they’d normally produce when they’re dirty.

Spray the panels with a hose if they’re a little dirty and there’s a drought. If you live in the desert or it hasn’t rained in a while, you may notice a layer of dust or dirt building up on your panels every month or so. When this happens, head outside and grab a garden hose. Use a nozzle attachment to spray water on your roof to rinse your panels off. Let them air dry when you’re done.
- You might also want to wash off your panels with a hose if you live someplace that has a lot of pollen, sandstorms, or ash.
- If your panels are really filthy and you have a flat roof, you can wipe them down with water and a cloth-covered sponge or squeegee. If your roof is pitched though, you may not want to clean them by hand unless you have a harness, roof anchor, and a personal fall arrest system. If you want the panels clean, you may be better off hiring a crew to do it.
- Do not wash your panels when it’s especially hot and sunny out. Wait for an overcast day or clean them early in the morning to keep the panels from experiencing abrupt temperature changes.
Knock snow off of the panels with a broom, squeegee, or leaf blower. If snow builds up on your panels and you have a roof access hatch, head up with a broom and knock the snow off from the hatch. If you have a flat roof, feel free to walk up there, but don’t leave the hatch if you have a pitched roof. Alternatively, you can get a squeegee with an extension rod and wipe the panels from the ground. If the solar panels are on a 1-story building, you can also use a leaf blower if the air reaches.
- If there’s a thin layer of snow and it will get sunny in the next day or so, don’t bother. The sun will slide off as the panels heat up in the sun. You really only need to remove snow during a prolonged period of heavy winter weather.
- Don’t worry about damaging the panels by wiping the snow off; they’re pretty resilient. So long as you aren’t using any abrasive cleaning methods the panels should hold up just fine.
Hire a professional cleaning crew to clean filthy panels on a pitched roof. If your panels get really dirty, you can’t reach them with a hose, or gunk is building up and you have a pitched roof, hire a cleaning crew that specializes in solar panels to come out and clean them thoroughly. It isn’t safe to get up on your roof on your own unless you really know what you’re doing. And even then, a professional crew will do a better job cleaning the complex panels.
- It isn’t that expensive to hire a crew for solar panel cleaning. Most companies charge $100-300 for a thorough cleaning.
- You really shouldn’t need to hire a crew to do this more than once a year.
- You can hire a contractor to install cleaning robots and automated systems that will do this kind of thorough cleaning automatically, but these systems can cost thousands of dollars and they’re typically unnecessary.
