The third general approach is to use renewable energy. Of the various renewable energy sources, by far the largest resource is provided by the sun. More energy from sunlight strikes the earth in 1 hr (4.3 × 1020 J) than all of the energy currently consumed on the planet in 1 yr (4.1 × 1020 J in 2001) (5). Yet, in 2001, only <0.1% of electricity and <1.5% of fuels (mostly from biomass) were provided by a solar source (1). Against the backdrop of the daunting carbon-neutral energy needs of our global future, the large gap between our present use of solar energy and its enormous undeveloped potential defines a compelling imperative for science and technology in the 21st century. With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bioethanol is widely used in the United States and in Brazil. The energy costs for producing bio-ethanol are almost equal to, the energy yields from bio-ethanol. However, according to the European Environment Agency, biofuels do not address global warming concerns.[74] Biodiesel is made from vegetable oils, animal fats or recycled greases. It can be used as a fuel for vehicles in its pure form, or more commonly as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Biofuels provided 2.7% of the world's transport fuel in 2010.[75] The journal, Renewable Energy, seeks to promote and disseminate knowledge on the various topics and technologies of renewable energy systems and components. The journal aims to serve researchers, engineers, economists, manufacturers, NGOs, associations and societies to help them keep abreast of new... Renewable energy, generally speaking, is clean energy and non-polluting.  Many forms do not emit any greenhouse gases or toxic waste in the process of producing electricity. It is a sustainable energy source that  can be relied on for the long-term. Renewable energy is cost-effective and efficient. The challenge of climate change has impelled many nations to set a renewable energy target. Our largest solar panel. Portable, rugged, and powerful. Designed for mobile basecamps and die-hard adventurers. Built-in charging cable for Sherpa Power Packs and Goal Zero Yeti Portable Power Station. Can be chained with other solar panels to collect more power from the sun. Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the https://www.youtube.com/edit?o=U&video_id=K0eWOm5aa_k heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage.[39] Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from seawater is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams.[40] Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes.[41] Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 °C (40 °F) and deliver outlet temperatures of 45–60 °C (113–140 °F).[42] The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems.[42] As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.[43] receives any excess energy you generate, and a feed-in tariff can allow you to get a credit on your bill for that excess electricity. You can also draw the extra electricity back from the grid if your system does not generate enough. Solar companies also contend with the complexity of the mobile-payment systems. In Ghana, where many customers don’t use mobile money, Poindexter’s Black Star team instead sells scratch cards from kiosks, which give customers a code they need to enter on their meter box to top up their account. Off-Grid delivers these codes over the phone, but the company still needs a call center, manned by fifteen people, to help customers with the mechanics of paying. Nena Sanderson, who runs Off-Grid’s Tanzanian operation, showed me the steps entailed in paying a bill through a ubiquitous mobile-money system called M-Pesa. There are ten screens, and the process ends with the input of a sixteen-digit code. “And I have a smartphone,” she said. “Now, imagine a feature phone, and imagine you may not know how to read, and the screen is a lot smaller, and it’s probably scratched up. Mobile money is a great enabler, but it’s not frictionless.” One of Off-Grid’s competitors, PEGAfrica, has printed the whole sequence on a wristband, which it gives to customers. Nearly all the gasoline sold in the United States today is mixed with 10% ethanol,[126] and motor vehicle manufacturers already produce vehicles designed to run on much higher ethanol blends. Ford, Daimler AG, and GM are among the automobile companies that sell "flexible-fuel" cars, trucks, and minivans that can use gasoline and ethanol blends ranging from pure gasoline up to 85% ethanol. By mid-2006, there were approximately 6 million ethanol compatible vehicles on U.S. roads.[127] Regarding energy used by vehicles, a comprehensive 2008 cost-benefit analysis review was conducted of sustainable energy sources and usage combinations in the context of global warming and other dominating issues; it ranked wind power generation combined with battery electric vehicles (BEV) and hydrogen fuel cell vehicles (HFCVs) as the most efficient. Wind was followed by concentrated solar power (CSP), geothermal power, tidal power, photovoltaic, wave power, hydropower coal capture and storage (CCS), nuclear energy and biofuel energy sources. It states: "In sum, use of wind, CSP, geothermal, tidal, PV, wave, and hydro to provide electricity for BEVs and HFCVs and, by extension, electricity for the residential, industrial, and commercial sectors, will result in the most benefit among the options considered. The combination of these technologies should be advanced as a solution to global warming, air pollution, and energy security. Coal-CCS and nuclear offer less benefit thus represent an opportunity cost loss, and the biofuel options provide no certain benefit and the greatest negative impacts."[11] Renewable energy projects in many developing countries have demonstrated that renewable energy can directly contribute to poverty reduction by providing the energy needed for creating businesses and employment. Renewable energy technologies can also make indirect contributions to alleviating poverty by providing energy for cooking, space heating, and lighting. Renewable energy can also contribute to education, by providing electricity to schools.[138] With the fire on Eugene Street, King says, everything went smoothly. But it was one of the department’s early encounters with solar installations, and they know there is more to learn. In a few weeks, some of their responders will go to a solar panel emergency seminar in the neighboring town of Litchfield. He also hopes to work more closely with the town building department on future installations. “So any projected use of them in the future, we have an opportunity to provide input and take into consideration the planning of the structure,” He says. Firefighters in Manchester haven’t run into many solar panels yet, but they plan to be prepared when they do. As the sun rises, you are paying for solar energy—typically at a lower rate—instead of energy from your utility company. For the energy you are not producing yourself, you pay the utility company the regular rate. For merchant solar power stations, where the electricity is being sold into the electricity transmission network, the cost of solar energy will need to match the wholesale electricity price. This point is sometimes called 'wholesale grid parity' or 'busbar parity'.[5] In 2015 hydropower generated 16.6% of the worlds total electricity and 70% of all renewable electricity.[45] Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy. There are many forms of water energy: Jump up ↑ A solar panel in the contiguous United States on average delivers 19 to 56 W/m² or 0.45 - 1.35 (kW·h/m²)/day."us_pv_annual_may2004.jpg". National Renewable Energy Laboratory, US. Retrieved 2006-09-04. Development of a solar-powered car has been an engineering goal since the 1980s. The World Solar Challenge is a biannual solar-powered car race, where teams from universities and enterprises compete over 3,021 kilometres (1,877 mi) across central Australia from Darwin to Adelaide. In 1987, when it was founded, the winner's average speed was 67 kilometres per hour (42 mph) and by 2007 the winner's average speed had improved to 90.87 kilometres per hour (56.46 mph).[79] The North American Solar Challenge and the planned South African Solar Challenge are comparable competitions that reflect an international interest in the engineering and development of solar powered vehicles.[80][81] The challenge is to expand the market for biofuels beyond the farm states where they have been most popular to date.[61] Flex-fuel vehicles are assisting in this transition because they allow drivers to choose different fuels based on price and availability. The Energy Independence and Security Act of 2007, which calls for 15.2 billion US gallons (58,000,000 m3) of biofuels to be used annually by 2012, will also help to expand the market.[60] [redirect url='http://affordsolartech.com/bump' sec='7']

    In a way, this step should actually come first, but having a good understanding of how solar works will help you better figure out your bill. There are currently three ways homeowners can add solar arrays to their property. The first is by simply purchasing an array and having it installed. The second is by leasing a solar array from a company that installs and maintains it, and the third is through a Power Purchase Agreement. Each method has its own variables and there are many companies operating in the space, so it’s impossible to generalize about which solution is the best one for you.
