Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate.
The wind is produced as a result of giant convection currents in the Earth's atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there's no electricity.
Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.
Expect lower expenses with your home’s energy consumption in the future with generating power method “boma fetching unique” (Google it). Its an excellent place to begin saving cash by making some small adjustments in your home. You can be a person who wants to save the environment or a family man wanting to save on bills, this is certainly among the best methods you`ll have.
*I am taking a course at the community college and use this book which is really excellent.If you are getting to Solar Energy, this [link here ::**https://plus.google.com/112513270274515701022/posts/EPufXhu4BoD** ] book is a must.*
Wind and Solar are not economically viable that is why they are subsidized with tax payer funds unless there's a major jump in technology. Geothermal and hydro are the most promising. and natural gas is a renewable in the form of methane. The carbon pollution from natural gas is very easily converted to a organic form by plants. Carbon pollution from that year will be neutralized by ocean plankton up to 20x estimated by some botanist and marine biologist more carbon then world produces today.
Great stuff! Nice work. The public really needs to see more of this. Have you heard anything about a new system called Optimal Future Energy Deployment (it should be on Google)? I’ve heard some interesting things about it and my brother got some amazing results. I’ve also been searching for solutions to the problem of wind turbines killing birds and bats. Ultrasonic acoustics looks like a possible answer to saving bats, but I haven’t read anything lately about the best way to keep birds away from wind turbines. Have you heard anything?
Problem with fusion is that the scientific consensus is that cold fusion is impossible and hot fusion involves pretty much making a star. Like, literally making a star. I think cleaner fission reactors (thorium!) is the way to go.
Solar is currently expensive but research is being done (by many people including me!) into cheaper ways to make cells.
the biggest problem we have with renewable energy plants is the amount of space they take up. e.g. a wide area around a wind tubine has to be completely empty because a. the danger of the wings or ice that forms in cold periods falling off and b. a wind turbine isnt as efficient went there are obstacles in the winds way and c. if wind turbines stand too close to one-another they create turbulences which can destabilise its structure. a few reasons why it is so hard to set them up correctly.
Although foreigners may now invest in A-shares, there is a monthly 20 percent limit on repatriation of funds to foreign countries.
Performance of A-shares.
Since its inception in 1990, including a major reform in 2002, the index has seen great fluctuations. Overall, however, it has grown along with the Chinese economy. The years 2015 to 2016 were a particularly difficult period, with a 52-week performance of -21.55 percent as of July 20, 2016.
As China grows from an emerging market to an advanced economy, there is substantial demand for Chinese equity. Stock exchange regulators continue efforts to make A-shares more broadly available to foreign investors and have them recognized by the global investing community.
In June 2017, the MSCI Emerging Markets Index announced a long-awaited decision it would add stocks to its index. According to CNBC, MSCI will add 222 China A Large Cap stocks to its benchmark emerging markets index gradually beginning in 2018. The MSCI website reveals the stocks it will list include the Bank of China, China Merchants Bank, Guotai Junan, Ping An Insurance, according to a document on Tsingtao Brewery, SAIC Motor, Suning Commerce and Spring Airlines.
Current Dividend Preference.
Participating Preferred Stock.
Convertible Preferred Stock.
Cumulative preferred stock includes a provision that requires the company to pay preferred shareholders all dividends, including those that were omitted in the past, before the common shareholders are able to receive their dividend payments.
Non-cumulative preferred stock does not issue any omitted or unpaid dividends. If the company chooses not to pay dividends in any given year, the shareholders of the non-cumulative preferred stock have no right or power to claim such forgone dividends at any time in the future.
Participating preferred stock provides its shareholders with the right to be paid dividends in an amount equal to the generally specified rate of preferred dividends, plus an additional dividend based on a predetermined condition. This additional dividend is typically designed to be paid out only if the amount of dividends received by common shareholders is greater than a predetermined per-share amount. If the company is liquidated, participating preferred shareholders may also have the right to be paid back the purchasing price of the stock as well as a pro-rata share of remaining proceeds received by common shareholders.
