Between mounting concerns about the environment and the rising cost of energy, there has never been a better time for Corpus Christi residents to invest in solar energy for their homes. Because these sources of energy are completely renewable, they make only a tiny impact on the environment, and they require almost no upkeep once they are installed. At Bodine-Scott, we offer a wide range of solar energy products to help our customers save money and protect the local environment from pollution.
The Solar updraft tower is a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a hot air updraft in the tower by the chimney effect. This airflow drives wind turbines placed in the chimney updraft or around the chimney base to produce electricity. Plans for scaled-up versions of demonstration models will allow significant power generation, and may allow development of other applications, such as water extraction or distillation, and agriculture or horticulture. A more advanced version of a similarly themed technology is the Vortex engine which aims to replace large physical chimneys with a vortex of air created by a shorter, less-expensive structure.
At an average cost to the end user of five cents per kilowatt hour, Juarez estimates Nemoi owners get a full return on their investment as soon as two years into ownership—if they received a rebate and they live in a windy area—or seven years at the longest, for no rebate and low-wind areas. He estimated the cost of installing solar panels for equivalent energy generation to be around $20,000.
With feed-in tariffs, the financial burden falls upon the consumer. They reward the number of kilowatt-hours produced over a long period of time, but because the rate is set by the authorities, it may result in perceived overpayment. The price paid per kilowatt-hour under a feed-in tariff exceeds the price of grid electricity. Net metering refers to the case where the price paid by the utility is the same as the price charged.

I contacted many different solar installation companies looking for someone who operates in my area (150 miles west of San Antonio) and Soleil Energy Solutions was the only one willing to make the trip out here. Fortunately for me, they’re also a great company to work with.I was able to deal directly with the owners of the company, Abbas and Jennifer, and their customer service is top notch. They had a customized assessment the day after I contacted them which included the size of system best suited for my home and energy consumption, the cost of the system with all the rebates and tax rebates I qualified for, and the amount of money I’d save on my light bill. They also offered me multiple financing options and guided me through that whole process. I had a ton of questions throughout the entire process and whether I emailed them or texted them after business hours, I got a response right away.They took care of everything for me including securing the rebates and city permits so I didn’t really have to do anything. The crew they had doing the actual solar panel and backup battery installation are all veterans, which I really appreciated because of their attention to detail. They were very courteous and they made sure the panels added to the curb appeal of my house as far as their placement.I’m really excited to finally have a solar panel system for my home and I’d definitely recommend Soleil to anyone who’s interested in switching to solar too.... read more
The International Renewable Energy Agency (IRENA) is an intergovernmental organization for promoting the adoption of renewable energy worldwide. It aims to provide concrete policy advice and facilitate capacity building and technology transfer. IRENA was formed on 26 January 2009, by 75 countries signing the charter of IRENA.[145] As of March 2010, IRENA has 143 member states who all are considered as founding members, of which 14 have also ratified the statute.[146]

Commercial concentrating solar power (CSP) plants, also called "solar thermal power stations", were first developed in the 1980s. The 377 MW Ivanpah Solar Power Facility, located in California's Mojave Desert, is the world’s largest solar thermal power plant project. Other large CSP plants include the Solnova Solar Power Station (150 MW), the Andasol solar power station (150 MW), and Extresol Solar Power Station (150 MW), all in Spain. The principal advantage of CSP is the ability to efficiently add thermal storage, allowing the dispatching of electricity over up to a 24-hour period. Since peak electricity demand typically occurs at about 5 pm, many CSP power plants use 3 to 5 hours of thermal storage.[65]
You should know that we at Solacity love wind turbines! Can’t get enough of ’em. Where the neighbours see life-threatening, blade-shedding, bat-and-bird killing, noise-making contraptions, we see poetry in motion. Kinetic art at its finest; combining form, movement, and function all in one. We could stare at them for hours, while contemplating the meaning of life, the universe, and everything… and have… until the beer ran out. Despite all the information presented here, we are big fans of small wind turbines. This page is about informing you, so you can make a decision based on fact and not marketing hype.
A regular alternator out of a car needs to be modified to produce anything meaningful above a few volts if any at low RPM. If this guy is not totally bullshit lieing, he is using a modified PMA alternator (permanent magnet alternator) and if not the voltage he is so proudly showing is actually a voltage drop caused by the alternator using power to power it's field coil. This is very misleading to newcomers to the field of renewable energy and makes a mockery of it. And if he really wanted to help people build this he would have should people how to wire the alternator up . Including explaining things like the wires on the regulator the ignition switch , the stator and the field wires. This is why rednecks laugh at liberals because they see shit like this. .

“Climate Change Helped Make California a Tinder Box for its Record-Setting Wildfires” • Camp Fire, which is devastating Sierra Nevada foothills, has become the most destructive wildfire in California’s history. By the evening of November 10, it had scorched 105,000 acres of land and killed 23 people, with more than 100 people still unaccounted for. [Quartz]
Another situation where a small wind turbine can make good sense is in case your province, state, or country has rebates or other incentives that make it cheap to install one (just keep ongoing maintenance and repair cost in mind as well). While we would like to advocate responsible spending of government money, the small wind industry needs many more customers to mature. It takes time and installation numbers for manufacturers to work out the bugs, make better turbines, and make them cheaper.

There are numerous organizations within the academic, federal, and commercial sectors conducting large scale advanced research in the field of sustainable energy. This research spans several areas of focus across the sustainable energy spectrum. Most of the research is targeted at improving efficiency and increasing overall energy yields.[94] Multiple federally supported research organizations have focused on sustainable energy in recent years. Two of the most prominent of these labs are Sandia National Laboratories and the National Renewable Energy Laboratory (NREL), both of which are funded by the United States Department of Energy and supported by various corporate partners.[95] Sandia has a total budget of $2.4 billion [96] while NREL has a budget of $375 million.[97]


The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator,[38][39] the control electronics, and most likely a gear box (e.g. planetary gear box),[40] adjustable-speed drive or continuously variable transmission[41] component for converting the low-speed incoming rotation to high-speed rotation suitable for generating electricity.
At GE, product evolution is at our core, and we are continuously working to develop the next generation of wind energy. Beginning in 2002 with one wind turbine model, we now offer a full suite of turbines created for a variety of wind environments. We offer increased value to customers with proven performance, reliability, and availability. Our portfolio of turbines feature rated capacities from 1.7 MW to 5.3 MW (Onshore) and 6 MW to 12 MW (Offshore), we are uniquely suited to meet the needs of a broad range of wind regimes. 
In 2007, the world's first turbine to create commercial amounts of energy using tidal power was installed in the narrows of Strangford Lough in Ireland. The 1.2 MW underwater tidal electricity generator takes advantage of the fast tidal flow in the lough which can be up to 4m/s. Although the generator is powerful enough to power up to a thousand homes, the turbine has a minimal environmental impact, as it is almost entirely submerged, and the rotors turn slowly enough that they pose no danger to wildlife.[48][49]
Biomass, biogas and biofuels are burned to produce heat/power and in doing so harm the environment. Pollutants such as sulphurous oxides (SOx), nitrous oxides (NOx), and particulate matter (PM) are produced from the combustion of biomass; the World Health Organisation estimates that 7 million premature deaths are caused each year by air pollution.[77] Biomass combustion is a major contributor.[77][78][79]

Energy storage is a collection of methods used to store electrical energy on an electrical power grid, or off it. Electrical energy is stored during times when production (especially from intermittent power plants such as renewable electricity sources such as wind power, tidal power, solar power) exceeds consumption, and returned to the grid when production falls below consumption. Pumped-storage hydroelectricity is used for more than 90% of all grid power storage. Costs of lithium ion batteries are dropping rapidly, and are increasingly being deployed as fast acting sources of grid power (i.e. operating reserve) and for domestic storage.
In 2004, the German government introduced the first large-scale feed-in tariff system, under the German Renewable Energy Act, which resulted in explosive growth of PV installations in Germany. At the outset the FIT was over 3x the retail price or 8x the industrial price. The principle behind the German system is a 20-year flat rate contract. The value of new contracts is programmed to decrease each year, in order to encourage the industry to pass on lower costs to the end users. The programme has been more successful than expected with over 1GW installed in 2006, and political pressure is mounting to decrease the tariff to lessen the future burden on consumers.

Which is to say that Ross and his co-workers had options. And the city was free to take advantage of them because of a rather unusual arrangement: Georgetown itself owns the utility company that serves the city. So officials there, unlike those in most cities, were free to negotiate with suppliers. When they learned that rates for wind power could be guaranteed for 20 years and solar for 25 years, but natural gas for only seven years, the choice, Ross says, was a “no-brainer.”
According to the International Energy Agency, new bioenergy (biofuel) technologies being developed today, notably cellulosic ethanol biorefineries, could allow biofuels to play a much bigger role in the future than previously thought.[41] Cellulosic ethanol can be made from plant matter composed primarily of inedible cellulose fibers that form the stems and branches of most plants. Crop residues (such as corn stalks, wheat straw and rice straw), wood waste and municipal solid waste are potential sources of cellulosic biomass. Dedicated energy crops, such as switchgrass, are also promising cellulose sources that can be sustainably produced in many regions of the United States.[42]
Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

There is more trouble with rated power: It only happens at a “rated wind speed”. And the trouble with that is there is no standard for rated wind speed. Since the energy in the wind increases with the cube of the wind speed, it makes a very large difference if rated power is measured at 10 m/s (22 mph), or 12 m/s (27 mph). For example, that 6 meter wind turbine from the previous section could reasonably be expected to produce 5.2 kW at 10 m/s, while it will do 9 kW at 12 m/s!
Wind turbines need wind to produce energy. That message seems lost, not only on most small wind turbine owners, but also on many manufacturers and installers of said devices. One of the world’s largest manufacturers of small wind turbines, located in the USA (now bankrupt by the way, though their turbines are still sold), markets their flag-ship machine with a 12 meter (36 feet) tower. Their dealers are trained to tell you it will produce 60% of your electricity bill. If you are one of those that is convinced the earth is flat, this is the turbine for you!
2010 was a record year for green energy investments. According to a report from Bloomberg New Energy Finance, nearly US $243 billion was invested in wind farms, solar power, electric cars, and other alternative technologies worldwide, representing a 30 percent increase from 2009 and nearly five times the money invested in 2004. China had $51.1 billion investment in clean energy projects in 2010, by far the largest figure for any country.[155]
Wind turbines are generally inexpensive. They will produce electricity at between two and six cents per kilowatt hour, which is one of the lowest-priced renewable energy sources.[72] And as technology needed for wind turbines continues to improve, the prices will decrease as well. In addition, there is no competitive market for wind energy, as it does not cost money to get ahold of wind.[72] The main cost of wind turbines are the installation process. The average cost is between $48,000 and $65,000 to install. However, the energy harvested from the turbine will offset the installation cost, as well as provide virtually free energy for years after.[73]
In 2011 Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, and Mark Delucchi published a study on 100% renewable global energy supply in the journal Energy Policy. They found producing all new energy with wind power, solar power, and hydropower by 2030 is feasible and existing energy supply arrangements could be replaced by 2050. Barriers to implementing the renewable energy plan are seen to be "primarily social and political, not technological or economic". They also found that energy costs with a wind, solar, water system should be similar to today's energy costs.[153]
“California Invests in ‘By Location’ Distributed Energy Resources” • California leads the US with several pilot projects to reward rooftop solar energy generators and other distributed energy resources in specific locations as an alternative to having utilities meet needs by investing in upgrading their electricity generation networks.

From 1978 to 1996, the National Renewable Energy Laboratory experimented with producing algae fuel in the "Aquatic Species Program."[112] A self-published article by Michael Briggs, at the University of New Hampshire Biofuels Group, offers estimates for the realistic replacement of all motor vehicle fuel with biofuels by utilizing algae that have a natural oil content greater than 50%, which Briggs suggests can be grown on algae ponds at wastewater treatment plants.[113] This oil-rich algae can then be extracted from the system and processed into biofuels, with the dried remainder further reprocessed to create ethanol. The production of algae to harvest oil for biofuels has not yet been undertaken on a commercial scale, but feasibility studies have been conducted to arrive at the above yield estimate. During the biofuel production process algae actually consumes the carbon dioxide in the air and turns it into oxygen through photosynthesis.[114] In addition to its projected high yield, algaculture— unlike food crop-based biofuels — does not entail a decrease in food production, since it requires neither farmland nor fresh water. Many companies are pursuing algae bio-reactors for various purposes, including scaling up biofuels production to commercial levels.[115][116]
Solar heating systems are a well known second-generation technology and generally consist of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage, and a reservoir or tank for heat storage and subsequent use. The systems may be used to heat domestic hot water, swimming pool water, or for space heating.[21] The heat can also be used for industrial applications or as an energy input for other uses such as cooling equipment.[22] In many climates, a solar heating system can provide a very high percentage (20 to 80%) of domestic hot water energy. Energy received from the sun by the earth is that of electromagnetic radiation. Light ranges of visible, infrared, ultraviolet, x-rays, and radio waves received by the earth through solar energy. The highest power of radiation comes from visible light. Solar power is complicated due to changes in seasons and from day to night. Cloud cover can also add to complications of solar energy, and not all radiation from the sun reaches earth because it is absorbed and dispersed due to clouds and gases within the earth's atmospheres.[23]
“California Wildfires: Trump Visits State’s Deadliest Blaze” • President Donald Trump went to California to survey the most destructive and deadliest wildfire in the its history. He said it had not changed his point of view on climate change, adding, “I want great climate and we’re going to have that and we’re going to have forests that are very safe.” [BBC]
The first words of everyone calling us are “the wind is blowing here all the time”. People consistently overestimate how windy their place actually is. They forget about all the times the wind does not blow, and only remember the windy days. Such is human nature. Before even considering a small wind turbine you need to have a good idea of the annual average wind speed for your site. The gold standard is to install a data-logging anemometer (wind meter) at the same height and location as the proposed wind turbine, and let it run for 3 to 5 years. Truth is that it is usually much too expensive to do for small wind turbines, and while logging for 1 year could give you some idea and is the absolute minimum for worthwhile wind information, it is too short to be very reliable. For most of us, the more economical way to find out about the local average wind speed is by looking at a wind atlas, meteorological data, airport information and possibly the local vegetation (for windy spots the trees take on interesting shapes).
Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. For countries having the largest percentage of electricity from renewables, the top 50 are primarily hydroelectric. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use. There are now three hydroelectricity stations larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela.[48]

If you can turn a wrench and operate an electric drill, you can build this simple generator in two days: one day for chasing down parts, and one day for assembling the components. The four major components include a vehicle alternator with a built-in voltage regulator, a General Motors (GM) fan and clutch assembly (I used one from a 1988 GM 350 motor), a tower or pole on which to mount the generator (15 feet of used 2-inch tubing cost me $20), and the metal to build a bracket for mounting the generator on the tower or pole. If you’re a Ford guy or a Mopar gal, that’s fine — just make sure your alternator has a built-in voltage regulator. You’ll also need some electrical cable or wires to hook the alternator up to your storage batteries. I used 8-gauge, 3-conductor cable pilfered from the oil patch. (And they said the transition from fossil fuels to renewables would take years. Pfft!)
Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. The 392 MW Ivanpah installation is the largest concentrating solar power plant in the world, located in the Mojave Desert of California.
