RENEWABLE ENERGY: THE CLEAN FACTS

Wind and sun oriented are controlling a perfect energy transformation. This is what you need to think about renewables and how you can help have an effect at home.
Solar Energy
Solar Energy
Sun powered, or photovoltaic (PV), cells are produced using silicon or different materials that change daylight straightforwardly into power. Disseminated galaxies create power locally for homes and organizations, either through roof boards or local area projects that power whole areas. Sun based ranches can produce power for a large number of homes, utilizing mirrors to think daylight across sections of land of sunlight based cells. Drifting sun based homesteads or "floatovoltaics" can be a successful utilization of wastewater offices and waterways that aren't naturally touchy. Sunlight based supplies somewhat more than 1% of U.S. power age. However, almost 33% of all new creating limit came from sun powered in 2017, second just to petroleum gas. Sun oriented energy frameworks don't create air toxins or ozone depleting substances, and as long as they are dependably sited, most sunlight based boards have not many natural effects past the assembling interaction.
Wind Energy
Wind Energy
We've made considerable progress from older style wind plants. Today, turbines as tall as high rises with turbines almost as wide in measurement prepare for action all throughout the planet. Wind energy turns a turbine's sharp edges, which takes care of an electric generator and produces power. Wind, which represents somewhat more than 6% of U.S. age, has become the least expensive fuel source in numerous pieces of the country. Top breeze power states incorporate California, Texas, Oklahoma, Kansas, and Iowa, however turbines can be put anyplace with high wind rates like ridges and open fields or even seaward in untamed water.
Hydroelectric Power
Hydroelectric Power
Hydropower is the biggest sustainable power hotspot for power in the United States, however wind energy is before long expected to assume control over the lead. Hydropower depends on water commonly quick water in an enormous waterway or quickly diving water from a high point and converts the power of that water into power by turning a generator's turbine sharp edges. Broadly and globally, huge hydroelectric plants or super dams are frequently viewed as nonrenewable energy. Uber dams redirect and decrease common streams, confining access for creature and human populaces that depend on waterways. Little hydroelectric plants (an introduced limit underneath around 40 megawatts), painstakingly oversaw, don't will in general reason as much natural harm, as they redirect just a negligible portion of stream.
Biomass Energy
Biomass Energy
Biomass is natural material that comes from plants and creatures, and incorporates crops, squander wood, and trees. At the point when biomass is singed, the compound energy is delivered as warmth and can create power with a steam turbine. Biomass is frequently erroneously portrayed as a spotless, inexhaustible fuel and a greener choice to coal and other non-renewable energy sources for creating power. In any case, late science shows that numerous types of biomass particularly from backwoods produce higher fossil fuel byproducts than petroleum derivatives. There are additionally unfortunate results for biodiversity. All things considered, a few types of biomass energy could fill in as a low-carbon alternative under the right conditions. For instance, sawdust and chips from sawmills that would some way or another rapidly deteriorate and discharge carbon can be a low-carbon fuel source.
Geothermal Energy
Geothermal Energy
In the event that you've at any point loose in an underground aquifer, you've utilized geothermal energy. The world's center is probably just about as warm as the sun's surface, because of the sluggish rot of radioactive particles in rocks at the focal point of the planet. Penetrating profound wells carries hot underground water to the surface as an aqueous asset, which is then siphoned through a turbine to make power. Geothermal plants commonly have low emanations on the off chance that they siphon the steam and water they use once more into the supply. There are approaches to make geothermal plants where there are not underground supplies, but rather there are worries that they may build the danger of a seismic tremor in regions previously viewed as topographical problem areas.
Nuclear
Nuclear
Atomic force, the utilization of supported atomic parting to create warmth and power, contributes almost 20% of the power produced in America. The United States has utilized atomic force for over 60 years to create solid, low-carbon energy and to help public protection exercises. The Energy Department's Office of Nuclear Energy's essential mission is to progress atomic force as an asset fit for making significant commitments in gathering our country's energy supply, ecological, and energy security needs. By zeroing in on the improvement of cutting edge atomic advances, NE upholds the Administration's objectives of giving homegrown wellsprings of secure energy, lessening ozone depleting substances, and upgrading public safety. Atomic force stays a significant piece of our country's energy portfolio, as we endeavor to diminish fossil fuel byproducts and address the danger of worldwide environmental change.
Bioenergy
Bioenergy
Biomass is a natural environmentally friendly power source that incorporates materials like farming and timberland buildups, energy yields, and green growth. Researchers and architects at the Energy Department and National Laboratories are discovering new, more productive approaches to change over biomass into biofuels that can replace ordinary fills like gas, diesel, and fly fuel. Bioenergy can help guarantee a monetarily strong and secure future while decreasing natural effects through: 1.Developing moderate homegrown fills and co-items 2. Propelling clean fuel sources 3.Generating homegrown responsibilities to help the development of the U.S. bioeconomy. Innovative work to change inexhaustible carbon and waste assets into feedstocks for transformation to biofuels, bioproducts, and bio power will reasonably grow biomass asset potential in the United States.
Hydrogen and Fuel Cells
Hydrogen and Fuel Cells
The Hydrogen and Fuel Cell Technologies Office (HFTO) centers around exploration, advancement, and exhibit of hydrogen and power module advances across various areas empowering development, a solid homegrown economy, and a perfect, evenhanded energy future. Hydrogen is the least difficult and most bountiful component known to man. It is found inside water, petroleum derivatives, and all living matter, yet it seldom exists as a gas on Earth—it should be isolated from different components. There are different homegrown assets that can be utilized to deliver hydrogen, including renewables (wind, sun oriented, hydropower, biomass, and geothermal energy), atomic force, and petroleum products (like flammable gas and coal – with carbon catch and sequestration). The U.S. at present creates in excess of 10 million metric huge loads of hydrogen each year, around one-seventh of the worldwide inventory.

But community solar markets are poised for expansion throughout the country. As you’re comparing your options, this article will help you evaluate community solar one community solar offer from another.

Key factors to compare in community solar offers

If you’re considering community solar, you probably hope to save money on your power bill, as you would if you were looking into rooftop solar. While all programs offer essentially the same environmental benefits, some community solar projects promise bigger savings than others. And even if you only have one option, you should clearly understand its benefits before signing anything (and don’t forget to compare it to the option of installing solar panels at your property!)

Below are some factors to consider and questions to ask when reviewing and comparing community solar offers:

How much solar energy do you need?

With community solar, you will be signing up for a ‘share’ (in kilowatts, kW) of the community solar project’s capacity. Your share’s solar output will vary from month-to-month, and usually be higher in summer, lower in winter. This means that in some months, your overall electricity costs may be more than they would have been without solar, while in others they will be lower. Over the course of a year, this balances out and allows most subscribers to save 5-15 percent on their annual electric bills. 

Most community solar providers will recommend a subscription share that will meet close to 100 percent of your current annual electricity needs. However, depending on your circumstances, you may be able to ask to have a smaller or slightly larger share. For instance, if you expect your electricity to fall in the future, you may want to ask for a smaller share in the project – this is usually easier to do this before signing up than after you subscribe. You don’t want to be stuck paying for solar electricity that you don’t need.

Similarly, if your electricity usage is likely to increase in the future, you may want to subscribe to a larger share. However, if you do so–and don’t end up using the extra electricity–you may not be able to recover those extra costs.

Is it an ownership-based program or subscription-based program?

Will you pay for the system up-front with cash or take out a loan to purchase your share of the community solar project (either a number of panels or a number of watts), or make ongoing payments for the electricity it generates under a ‘subscription’ model? Subscription-based programs are by far the most popular option, so don’t be surprised if there aren’t ownership-based programs available in your area.

Questions about subscription-based programs

Subscription-based programs come in a variety of forms, but you can compare them against one another by looking at estimated savings over a set period of time. Some programs offer more certainty about future savings than others. Also, penalty fees for early termination of a contract will vary by subscription.

Prior to signing up for a subscription, remember to ask:

When will you start saving money?

Some programs may start you at a community solar subscription rate that is higher than your utility rate, promising that you’ll save eventually as inflation drives higher utility rates. They may also include an escalator for the rate you’ll pay for solar credits, albeit at a lower annual percentage (e.g. 2.5 percent). Other programs will set a fixed, flat rate for solar, or offer a fixed discount on all the solar energy you buy (i.e. 10 percent less than utility rates.) If you have a choice, fixed flat rates and fixed discounts offer the most certainty for what you will pay throughout the duration of the program.

Is there an upfront fee to join the program?

If so, how much is it, and how far into the future will it push the point at which you start saving? Fortunately, most community subscriptions are free to sign up for – but it doesn’t hurt to double check!

Will you be penalized for late payments?

Receiving electricity from a community solar project is not always the same as buying energy from public utilities, so you may not have the same protections in place if you happen to run behind on your bills. Check the terms of your contract so that you’re prepared for this scenario.

Can you cancel your subscription at any time? And are there any penalty fees for an early exit from the program?

Many community solar providers allow you to terminate your subscription at any time, but may require a minimum cancellation notice or a small fee to do so.

Can you transfer your subscription to your new address if you move?

Most community solar programs will let you ‘take it with you’ at no additional fee if you move within the same utility area.

Can you take the panels home with you at the end of the term?

Although you do not technically ‘own’ the panels in the array, some programs will let you take your share of panels home after the project is decommissioned. It’s better to consider this more of a friendly ‘bonus’ rather than a core benefit for signing up, however.

Questions about ownership-based programs

Purchasing a share in a community solar project is like making an investment in a rooftop solar system: you make a payment now in order to save money on future power bills.

Before signing on the dotted line, ask yourself:

What’s the gross cost per watt ($/W)?

Knowing the $/W price for a share will allow you to meaningfully compare pricing offers.

Are you eligible for any tax incentives or rebates?

This will depend on what’s available in your state and utility, as well as the pricing structure of the project itself. 

How much will you pay for electricity after buying a share?

What rate will your utility credit you for generating solar power? Does it fluctuate over time, or stay flat? In most cases, this will be dictated by the state’s net metering policy.

Are there any additional fees? Ongoing or upfront?

Maintenance and administration costs are usually included in the purchase price, but it’s important to confirm because moving forward.

Can you get a loan?

Solar loans can be a good option if you don’t have the spare capital to pay for a community solar share upfront. In the best-case scenario, you could pay zero down while saving money from the beginning, eventually owning your share of the solar project.

What’s the estimated payback period?

How long will it take before you recoup your initial investment? All of the above factors will play a role in determining this. A good quote will give a transparent, conservative estimation of payback time.

Can you take the panels with you at the end of the term?

Ownership-based programs will generally let you take your share of panels home after the project is decommissioned (but not before!) At that point you may use them as you wish, but keep in mind that the panels are just one small part of what you paid for initially (inverters, cables and mounting equipment). Think of this as a small ‘bonus’ for participating in the project.

How do the costs and savings compare to installing a rooftop system?

If your roof is a good fit for solar panels, we recommend comparing in installation options for your property before making a decision to buy a share of a solar project.
