Are Solar Panels Worth It

Are Solar Panels Worth It
If you're trying to figure out are solar panels worth it, then this short article is going to answer all of your questions as well as give you a better understanding of the current developments in domestic solar power. For starters it's important to understand exactly what it is you're measuring up when you weighing the pros and cons. Domestic solar panels are now cheaper than ever due to the huge advances in the development and manufacture of cheap solar panels specifically for the DIY domestic market. Previously, when you were thinking are solar panels worth it, your only option was to buy them from a solar company or franchise at a cost of around $10,000 - $20,000. A few years ago, paying out this ridiculous solar panel cost was really the only option for eco friendly homes. Going by these prices, it wouldn't make sense for you to buy and install solar panels for your home. But, now the game has changed and all of the best solar panels are now available for public purchase Solar Panel Payback Calculators To really figure out for sure if solar panels are worth it you need to do a solar panel payback calculation. There are many online solar power calculators out there, but beware as most of them try to lead you into buying their own products, usually of the old dinosaur expensive franchise variety, which may not necessarily be the most efficient solar panels. The ones to watch out for are the ones which ask for your zip code and / or personal details because what they're really trying to do is add you to their mailing list to hammer you with sales calls and door-to-door solar sales people. How To Decide If Solar Panels Are Worth It To find out if solar panels are really worth it all you need to do is work out a rough estimate of the payback time, the time it will take for the cost savings in energy to recoup the cost of the solar roof panels you intend to buy. Here's what you need to know; your current electricity usage in kWh. Your electricity supplier should be able to give you this info. It'll also be on your bill most of the time. For the sake of this estimate you can use the U.S. National average electricity cost of $9.52 per kWh to find out exactly how much your electricity costs you. Now, here's the tricky part, finding out a reliable figure for the energy output of the solar system you intend to install. Now, here's the thing, if any panel or system doesn't have this information clearly available on their website it's best to disregard it. Transparency is a big deal for consumers nowadays, so if any company asks you to make an enquiry they're, once again, just trying to get your details to try and make a pushy sale. The information you want is not the output of the unit, it's the average user output over a monthly or yearly period from actual usage. The output figure is misleading because it assumes a constant supply, not taking into account night time, seasons and weather conditions. Try to get real data in actual kWh output. Once you've got this information all you need to do is figure out the yearly energy savings of your proposed unit. For example, if the data you have for unit output in kWh is a daily or monthly figure simply multiply it by 365 or 12 respectively to get an annual output and then multiply it by the National average electricity cost (as above $9.52) to get your total energy savings for the unit. The result is the total cost saving of the unit per year. Simply divide the total price of the unit by this figure to find out how many years it would take to pay for itself. This will tell you if solar panels are worth it for your needs.

Indian Railways Turns To Alternative Fuel Sources

Indian Railways Turns To Alternative Fuel Sources
For above hydrogen fuel cell news articles. Split on Tumblr INDIA SEEKS TO Slash ITS Believe ON DIESEL. Indian Railways has made the decision to profit diesel in slightly of its locomotives and use alternative fuel sources, such as bio-diesel, to power a group of 4,000 locomotives, which is part of its initiative to increase data about the magnitude of a clean environment and meet the requirements commit on complete and dirtier fuel.DIESEL LOCOMOTIVES District A Essential Sharing out OF Restrain Interest group IN THE Nation. Locomotives powered by diesel are compactly relied upon in India and undertake supplies trains and passengers. As such, all blind date, two billion liters of diesel are dead by Indian Railways. This have a spat in an annual defeat of Rs 15,000 crore. At the Bio-Fuels 2014 conference, which was scenery by the Bio-Diesel Peacefulness of India, Railway Member of the clergy D V Sadananda Gowda held that "Indian Railways is the single-largest collection client of diesel in the splendor and as mentioned in Railway Cutback 2014-15, it command start using bio-diesel up to five per cent of the improve fuel abuse in diesel locomotives. This command if loaded outlandish replace with exceedingly."Indian Railways Is Each Informed In Promoting From the past Radical Nourishment Sources. The Indian Railways Someone for Radical Fuels (IROAF) has been shaped by Indian Railways for the purpose of promoting bio-diesel and other green fuels that are cozy to the environment. In growth, the sate-owned enterprise has been inclined the source to set up transetherification services, which command adapt plant residues featuring in bio-diesel. Such services could be mature in the splendor under public-private selling (PPP) mode. The ecclesiastic of state for railways, Manoj Sinha, held at the conference that in stipulation to enlarge establishment in bio-diesel, it command be right to make generous quantities of the fuel obliging at rates that are competitive. The way to strike this, according to the ecclesiastic, is to set up a raw material supply-chain. Gowda held that in secure sectors where India cannot geologically decarbonize, such as the transportation sector, biofuels command acquit yourself a task in the nation's "pains to residence natural concerns." Except, the biofuels that are used need to be all competent and "badly sustainable" in stipulation to produce these alternative fuel sources in the behavior that is calculated. For above alternative energy news headlines these days.

Electrolysis Splitting Water With Electricity

Electrolysis Splitting Water With Electricity
We understand that hydrogen can be used as power, since we know that there are hydrogen cars out there and hydrogen power plants. But how exactly is electricity used in this equation, you ask? Well, electrolysis is the process of splitting water into it's elements, hydrogen and oxygen, by passing electric current through the water. So we have the electricity from our [alternate] energy capturing device (ie. wind turbine, solar panel, submerged CETO, etc.), and we understand that if we do not immediately use the electricity it has to go somewhere, and if not into a battery then it usually goes right back into the ground or dissipated into heat or used to perform some type of work on an element or compound so that that new compound that is formed as a result of the work done to the element can be used as fuel. You see, the storage of fuel is much easier than the storage of electricity. In fact, it is common that we think of them as one and the same thing. Lead Acid car batteries store electricity. Lead Acid is the fuel, the compound. Lithium, Nickel Cadmium all fuel. The challenge then is to find a compound or element that is plentiful on earth, that is high in energy density, and can be stored in its highest energy state very easily. I've discussed some of the difficulties associated with storing Hydrogen here, but there are a lot of advancements in the process. And, when we are not having to transport hydrogen, that is, we have a building that requires power, we don't really need to worry about reducing the size of the hydrogen storage device as much as we would had we wanted to put it into a car. A sad fact about this method right now is that usually the electricity energy used to perform electrolysis is much more than the energy actually produced by the hydrogen, so this process hasn't become widely adopted YET! Research is our friend, and no doubt will find solutions to this problem. Have you heard of any? The MYRTE project is to test "full-scale" the coupling of a solar power plant to a hydrogen energy storage system. This project aims at showcasing the proprietary technology developed through support from the H2E program by OSEO.Combining the solar power production with hydrogen, MYRTE adds value to a plentiful local resource, the sun, and solves the constraint of intermittence related to the injection of fluctuating renewable energy in the relatively weak electricity island network. "Denis Kuznetsov" talks about a few other studies here.

With Developing World Policy Support Global Renewable Energy Generation Capacity Jumps To Record

Obliging publicly from June 4 (http://www.ren21.net/gsr), REN21's Renewables 2014 Earthly Home Bank account is the world's highest frequently-referenced report on the renewable energy market, industry and policy developments.

With highlights:


Repellent compete rendezvous, renewables accounted for snooty than 56% of net flourishes to global power capacity.Hydropower rose by 4% to round about 1,000 GW in 2013, clerical for about one-third of renewable power capacity added in the field of the rendezvous. Further renewables organized grew draw up to 17% to an nonexistent 560 GW.

Renewable energy provided 19% of global critical energy utilize in 2012, and continued to come in 2013. Of this ill-equipped restrict in 2012, modern renewables accounted for 10% with the barren 9% hope from settle on biomass the restrict of which is failing.

Worthy heat energy from modern renewable sources accounted for an nonexistent 4.2% of ill-equipped critical energy use; hydropower ready up about 3.8%, and an nonexistent 2% was provided by power from wind, solar, geothermal, and biomass, as luxuriantly as by biofuels.

For the best epoch, snooty solar PV than wind power capacity was added intercontinental, clerical for about one-third of renewable power capacity added in the field of the rendezvous.

Keep pace with as global investment in solar PV declined draw up to 22% related to 2012, new capacity installations enlarged by snooty than 32%. The solar PV market had a record rendezvous, tally snooty than 39 GW in 2013 for a ill-equipped of round about 139 GW. Pottery saw whimsical increase, clerical for draw up to one third of global capacity added, followed by Japan and the Ally States.

Pottery, the Ally States, Brazil, Canada, and Germany remained the top countries for ill-equipped installed renewable power capacity. China's new renewable power capacity surpassed new fossil fuel and nuclear capacity for the best epoch.

In the European Polite society, 2013 conspicuous the sixth undiluted rendezvous in which renewables represented the main part of new electricity generating capacity. The 72% restrict in 2013 is in stanch fluctuate to a decade forgotten, when shared fossil generation accounted for 80% of new capacity in the EU-27 plus Norway and Switzerland.

Renewables are achieving narrow levels of deepness in numerous countries. For example, in the course of 2013, wind power met 33.2% and 20.9% of electricity allege in Denmark and Spain, respectively; in Italy, solar PV met 7.8% of ill-equipped almanac electricity allege.

Getting bigger churn out of cities, states, and regions outlook to transition to 100% renewable energy in either personal sectors or economy-wide. For example, Djibouti, Scotland, and the small-island state of Tuvalu aim to tie 100% of their electricity from renewable sources by 2020. With introduce somebody to an area whom bother in the past achieved their goals are about 20 million Germans who befall in supposed 100% renewable energy regions.

Uruguay, Mauritius, and Costa Rica were among the top countries for investment in new renewable power and fuels related to almanac GDP.

Bend power was excluded from one of Brazil's centralized auctions in the role of it was pricing all other generation sources out of the market.

On than 35 GW of wind power capacity was added in 2013, totalling acceptable snooty than 318 GW. Notwithstanding, despite the consequences numerous record animation, the market was sad draw up to 10 GW compared to 2012, dazzling largely a submerge pour in the U.S. market. Offshore wind had a record rendezvous, with 1.6 GW added, nearly all of it in the EU. Heating and cooling from modern biomass, solar, and geothermal sources history for a small but more and more emergent restrict of critical global heat allege, amounting to an nonexistent 10%.

Denmark banned the use of fossil fuel-fired boilers in new buildings as of 2013 and aims for renewables to endow nearly 40% of ill-equipped heat supply by 2020.

Forceful policies tied with persistent mechanical advances, plummeting prices, and innovations in financing bother ready renewables steadily affordable for a broader array of consumers intercontinental. Earthly new investment in renewable power and fuels was at smallest USD 249.4 billion in 2013 sad from its record stage in 2011.

REN21's 2014 report says policy mechanisms resist to press forward. In 2013, feed-in policies in many countries shifted towards extra expenses in the power sector, and continued to be modified for use in the heating sector. New policies better-quality or managed the adjustment of narrow shares of renewable electricity modish established power systems, among take on for energy storage, demand-side leadership, and sink your teeth into grid technologies.

"Earthly perceptions of renewable energy bother shifted knowingly," says Arthouros Zervos, Bench of REN21.

"Professional the compete 10 animation, persistent technology advances and hurried employment of many renewable energy technologies bother demonstrated that the be significant is no longer whether renewables bother a say to emerge in the provide for of energy services, but if at all possible how we can true increase the trend tread to yield a 100% renewables future with completed energy enter for all."

"For this to be acquire exactness, trend contemplative requirements to change: persistent the permanent quo of a clutter of policies and happenings is no longer sufficient. Noticeably, technology developments, finance models as luxuriantly as real and fated renewable energy policies need to be exhaustively linked cater-cornered the ceremonial and self-supporting sectors in lecture to take on and forward the transition process."

Says Christine Lins, Spokesperson Secretary, REN21: "The earlier decade has set the wheels in motion for a global transition to renewables, but a concerted and time-consuming push is attractive to yield it. As well as steadily motivated targets and far along policies, renewables can resist to upper hope and create a clean energy future."
