斗地主达人Solar Power for Homes and its Benefits

Modern technology can do a lot of great things。 One is the use of solar power for homes。 Did you know that you can enjoy many benefits from using solar power? Solar panels can now be created at home by simply following comprehensible do-it-yourself instructions。 Building power systems is no longer very expensive these days and it’s also not as hard as you think。

斗地主达人With the increasing demand for solar powered homes, you can now find a wide range of DIY projects in the market. The reasons why many homeowners are now choosing solar power for their homes is because they want to help in the persistent global warming crisis and electric bills cost a lot these days.

The electricity supplied in modern homes usually comes from different power plants。 These power plants use fossil fuels and so the electric charges are greatly dependent on the prices of natural gases and crude oil。 Fossil fuels are also depleting。 There is a high demand for electricity but the resources have decreased greatly。 In this kind of situation, the electrical costs will still continue to increase。 The solar power for homes is an excellent answer to the problem。

By using fossil fuels, the problem with global warming will become worse. Harmful gases are emitted by the fossil fuels to produce electricity. If you don’t want to contribute to the environmental problems any further, why not use solar power for your home now?

Several years ago, the solar cells were really expensive and inefficient. Back then the solar cells were quite inefficient since they can’t convert 100% of the rays of the sun into electricity. Most solar cells can convert only 10-25%. In the year 2003, a new product was introduced and it was called photovoltaic cell. The new cell can convert 36% of the rays into usable electricity. The cells were also affordable. The modern sunlight technology is now widely available and even ordinary homeowners can take advantage of it.

The solar power kits are available worldwide. You can purchase them in online stores or you can also shop around in local stores. If you’re unsure, it would be best to shop online. There you can find several reputable sellers and manufacturers of solar power kits.

The solar power kits provide step by step instructions on how to assemble the different materials。 Hardware stores usually sell the different parts of the solar power system。 If create your own solar power system, you will only spend about $200 and it already includes the guide。 With such a small investment, you can already benefit from solar power for many years。 You’re not only saving money but you’re also helping in saving the planet。

Renewable and clean energy sources are in great demand these days. The homes of the future are now possible in today’s modern world. You can start with small projects and work your way up. For instance, you can first work on the outdoor lighting first and if it proves to be beneficial, you can do another project.

Don’t cut off the existing electrical supply especially if this is your first time to do solar power projects. Just use it as a supplement so that you can lessen your electricity consumption. Start with your DIY solar power project and light your home using the sun’s energy.

Sustainable Power Of The Wind

A Brief Lesson in History

A sustainable energy source since ancient times, the power of the wind has been harnessed by sailors, farmer, and architects alike. In times long gone, from 5,000 years ago and rediscovered again today the Egyptians used wind power to propel their sailing vessels, and Babylonian architects use architectural designs to make use of the wind to ventilate their palace and temple complexes.

As early as 300 B.C. the Sinhalese bygones used monsoon winds to power their furnaces. Constructed right where monsoon winds pass the furnaces were powered up to 1100 to 1200 centigrade. In the 1st century AD the first ever primitively built windmill was used to power an organ. Later during the 7th century the first and most primary windmill was built in Afghanistan in a small town called Sistan. The Windmill has a vertical axle with blades shaped like a rectangle and with a long driveshaft. In the 1100’s wind mills were built to grind flour, for sugar manufacturing and the gristmilling industries. The Dutch built windmills that stand until this day.

Beneath Power Is Wind

The Sun unevenly heats the Earth that differences of heat distribution; the poles receive less than the equators do. Unlike the land, the oceans, seas and rivers do not have covering so it retains more heat than soil. This contrast results in a global atmospheric convection that reaches from the stratosphere and into the earth’s surface. Energy in these wind movements are stored at high altitudes where in the wind can achieve speeds up to 160km/hr. Here after with the effects of friction the wind’s energy is diffused into heat throughout the planet and its atmosphere. This vast amount of sustainable power can provide us unimaginable amounts of energy, far more than we currently consume.

Wind Speed Distribution

Wind varies in strength. The average value of a certain location does not specify the energy of a single wind turbine. The wind speed’s frequency can be assessed in a particular location, they are fitted by a probable distribution function to the particular observed data. Different wind distributions varies from different locations, hourly wind speeds at different locations are being monitored by the Rayleigh model, which basically means a continuous probability distribution which was named after Lord Rayleigh.

Electrical Generation

Using the power of electricity from a wind farm is usually fed through a network of electrical power transmissions。 This is done by connecting the individual turbines with a medium voltage power system and a series of communications networks。 The electrical current is then increased with a transformer to be able to connect to the high voltage transmitting system。 System operators supplies the wind farm owner with a code that indicates requirements to be able to connect to the transmission grid which includes the power factor, the constancy of the frequency and the behavior of the wind turbines when experiencing system faults。

Now that we know that the speed of wind is not constant, a farm’s energy production is not as much as the sum of the nameplate rating being multiplied by the year’s total hours being used。 The ratio of this productivity in a whole year is called the capacity factor。 This is the ratio of productivity in a year to this theoretical maximum。
