The main developer for the park’s plan is a company called Himin Solar Energy. It was started by Huang Ming who is often called the ‘Sun King’ of China. Although he says: “I prefer to be called solar madman.” The building that serves as headquarters for Himin Solar Energy is located at the Sun-Moon Mansion and is currently the largest solar powered office building in the world.

An intriguing mix of raw capitalism and socialist planning is giving companies such as Huang’s Himin Solar Energy Group a shot at making a difference.
The city of Dezhou already requires that all new buildings be equipped with solar water heaters (the type made by Huang’s company). Last year they spent $10 million to install solar lighting along several miles of road.
Huang’s company is the world’s biggest producer of solar water heaters. It recently opened a low-carbon five-star hotel and is building Utopia Garden, a gigantic, eco-friendly luxury apartment complex – both with solar-heated pools.
“Renewable energy doesn’t mean people have to be uncomfortable,” Huang states.

Last year, China invested about $34 billion in solar panels, wind turbines and other alternative energy technologies, nearly twice as much as the United States, where green technologies spending unfortunately fell sharply.
Huang notes that, so far, solar energy is “a drop in the ocean” on the road to the major Environmental and Economical changes but he said that Dezhou offers a model for the future. “I like big plans,” he says.

Here’s an easy way to learn the way solar panels work.

What is solar power?

Solar energy is radiant energy that is produced by the sun. Daily the sun radiates, or sends out, a huge amount of energy. The sun radiates more energy in a single second than people have used since the beginning of time!

The energy of the sun derives from within the sun itself.

Like other stars, the sun is a big ball of gases––mostly hydrogen and helium atoms. The hydrogen atoms in the sun’s core combine to create helium and generate energy in a process called nuclear fusion.

During nuclear fusion, the sun’s extremely high pressure and temperature cause hydrogen atoms to come apart and their nuclei (the central cores of the atoms) to fuse or combine. Four hydrogen nuclei fuse to become one helium atom. However the helium atom contains less mass than the four hydrogen atoms that fused. Some matter is lost during nuclear fusion. The lost matter is emitted into space as radiant energy.

It takes countless years for the energy in the sun’s core to make its way to the solar surface, and somewhat over eight minutes to travel the 93 million miles to earth. The solar energy travels to the earth at a speed of 186,000 miles per second, the speed of light.

Simply a small percentage of the power radiated by the sun into space strikes our planet, one part in two billion. Yet this volume of energy is enormous. Each day enough energy strikes the United States to supply the nation’s energy needs for one and a half years!

Where does all this energy go?

About 15 percent of the sun’s energy that hits our planet is reflected back into space. Another 30 percent is used to evaporate water, which, when lifted into the atmosphere, produces rainfall. Solar power also is absorbed by plants, the land and the oceans. The remaining could be employed to supply our energy needs.

Who invented solar energy?

Humans have harnessed solar power for hundreds of years. As early as the 7th century B.C., people used simple magnifying glasses to concentrate the light of the sun into beams so hot they would cause wood to catch fire. More than a century ago in France, a scientist used heat from a solar collector to make steam to drive a steam engine.

At the beginning of the 20th century, scientists and engineers began researching ways to use solar energy in earnest. One important development was a remarkably efficient solar boiler introduced by Charles Greeley Abbott, a United States astrophysicist, in 1936. The solar hot water heater became popular at this time in Florida, California, and the Southwest. The industry started in the early 1920s and was in full swing right before World War II. This growth lasted up to the mid-1950s when low-cost gas had become the primary fuel for heating American homes.

People and world governments remained largely indifferent to the possibilities of solar power until the oil shortages of the 1970s. Today, people use solar energy to heat buildings and water and to generate electricity.

How we use solar power today?

Solar power is employed in a variety of ways, of course. There are two very basic types of solar energy:

* Solar thermal energy collects the sun’s warmth through one of two means: in water or in an anti-freeze (glycol) mixture.

* Solar photovoltaic energy converts the sun’s radiation to usable electricity.

Listed below are the five most practical and popular solutions on how solar energy is employed:

1. Small portable solar photovoltaic systems. We see these used everywhere, from calculators to solar garden products. Portable units may be used for everything from RV appliances while single panel systems are used for traffic signs and remote monitoring stations.

2. Solar pool heating. Running water in direct circulation systems via a solar collector is a very practical solution to heat water for your pool or hot tub.

3. Thermal glycol energy to heat water. In this method (indirect circulation), glycol is heated by sunshine and the heat is then transferred to water in a hot water tank. This technique of collecting the sun’s energy is much more practical now than in the past. In areas as far north as Edmonton, Alberta, solar thermal methods to heat water are economically sound. It can pay for itself in three years or less.

4. Integrating solar photovoltaic energy into your home or office. In many parts of the planet, solar photovoltaics are an economically feasible approach to supplement the power of your own home. In Japan, photovoltaics are competitive with other types of power. In the USA, new incentive programs make this form of solar power ever more viable in many states. An increasingly popular and practical way of integrating solar energy into the power of your home or business is through the use of building integrated solar photovoltaics.

5. Large independent photovoltaic systems. When you have enough sun power at your site, you may be able to go off grid. You may also integrate or hybridize your solar power system with wind power or other forms of renewable energy to stay ‘off the grid’.

How do Photovoltaic panels work?

Silicon is mounted beneath non-reflective glass to produce photovoltaic panels. These panels collect photons from the sun, converting them into DC electric power. The energy created then flows into an inverter. The inverter transforms the energy into basic voltage and AC electrical power.

Solar cells are prepared with particular materials called semiconductors like silicon, which is presently the most generally used. When light hits the photovoltaic cell, a particular share of it is absorbed inside the semiconductor material. This means that the energy of the absorbed light is given to the semiconductor.

The energy unfastens the electrons, permitting them to run freely. Solar power cells also have more than one electric field that act to compel electrons unfastened by light absorption to flow in a specific direction. This flow of electrons is a current, and by introducing metal links on the top and bottom of the Photovoltaic cell, the current can be drawn to use it externally.

Do you know the positives and negatives of solar technology?

Solar Pro Arguments

- Heating our homes with oil or natural gas or using electricity from power plants running with fossil fuels is a reason behind climate change and climate disruption. Solar power, on the other hand, is clean and environmentally-friendly.

- Solar hot-water heaters require little maintenance, and their initial investment may be recovered within a relatively small amount of time.

- Solar hot-water heaters can work in almost any climate, even in very cold ones. You just have to choose the best system for your climate: drainback, thermosyphon, batch-ICS, etc.

- Maintenance costs of solar powered systems are minimal and the warranties large.

- Financial incentives (USA, Canada, European states…) can aid in eliminating the price of the initial investment in solar technologies. The U.S. government, as an example, offers tax credits for solar systems certified by by the SRCC (Solar Rating and Certification Corporation), which amount to 30 percent of the investment (2009-2016 period).

Solar Cons Arguments

- The initial investment in Solar Water heaters or in Solar PV Electric Systems is higher than that required by conventional electric and gas heater systems.

- The payback period of solar PV-electric systems is long, as well as those of solar space heating or solar cooling (only the solar domestic hot water heating payback is short or relatively short).

- Solar water heating does not support a direct conjunction with radiators (including baseboard ones).

- Some air-con (solar space heating and the solar cooling) systems are very pricey, and rather untested technologies: until recently, solar air-con has not been an economical option.

- The efficiency of solar powered systems is determined by sunlight resources. It is in colder climates, where heating or electricity needs are higher, that the efficiency is smaller.

In the vocabulary of our modern world, the term “organic gardening” has become widely popular in gardening magazines, books, on the World Wide Web and in everyday conversations.
While growing without chemicals is trendy now, it has been around since ancient times. It was the only way to farm. After all, chemical fertilizers weren’t even a possibility until the 1840’s.
So, what exactly is organic gardening? And how is it beneficial to us?

In plain words, organic gardens don’t get fertilized with synthetics; only animal or vegetable fertilizers are used.
Natural pest control methods are used, as opposed to industrial insecticides. In other words only natural substances and beneficial insects are used to ward off pests instead of spraying with potentially harmful commercial chemical substances.

Tatiana Starines has been enjoying organic gardening for over 70 years.
And just look at the results!

6 major benefits of organic gardening:

1. The harmful and toxic chemicals that we spray on our produce also seep into the ground, thus affecting insects that are beneficial. These chemicals also find their way into the air, waterways, sewers, lakes and streams. Organic gardeners create a mini “eco-system” that will maintain a healthy balance of soil and contribute to the health of our planet by not putting long-lasting, toxic chemicals into the air, soil and watershed. This makes organic gardening beneficial for everyone.
2. Organic gardeners contribute to preserving diversity. The loss of a large variety of species (biodiversity) is one of the most pressing environmental concerns. The good news is that many organic farmers and gardeners have been collecting and preserving seeds, and growing remarkable varieties for decades.
3. It is no-brainer that the natural health of the soil will produce healthy fruits and vegetables for your table. Organically-grown food is more nutritious than food grown using conventional methods. In humans, healthy and balanced nourishment increases strength of the immune system and minimizes the risks of potentially deadly diseases.
4. There is evidence of physical and emotional human benefits with organic gardening. “muscle-power” rather than “machine-power” burns more calories. You definitely will be in great shape and stress-free (horticultural therapy), when you spend quality time in your garden.
5. Organic gardening greatly reduces your exposure to pesticides, which have been linked to many severe health problems.
6. Growing your own healthy produce saves your household money in the long run.

Organic growing is much more than not using pesticides or insecticides. It is a philosophy that stresses on increasing the natural health of the soil, choosing suitable plants that are appropriate for your area, and working with nature to create a healthy and productive garden.

It only makes sense to use appropriate and eco-friendly lighting, such as solar lights, in your organic garden. Solar lights are easy to install (no wiring) and they are charged by the energy of sun (free, renewable, eco-friendly energy). Solar lighting is ideal for areas where conventional electrical supply is not available. They are a simple way to accentuate your trees, pathways and flower beds!
With the latest solar technology developments, the solar industry has moved forward substantially. Now we have a cool variety of choices when picking appropriate solar lighting for your organic garden.

Some of them are really bright (solar spot light) and will accentuate the beauty of your trees or large bushes.

Others release a soft and pleasantly scattered light that looks great around your pathways and flowerbeds.
A great selection of solar garden lights can be found here. While choosing an appropriate solar lighting solution for your garden, pay attention to the solar product descriptions to make sure you get what best suites your garden needs. See solar gardens image galleries HERE.

Starting and maintaining an organic garden is simple and easy with a little knowledge and patience.
Growing your own organic garden is something you can take great pride and pleasure in.

The Solar Decathlon, run by the US Department of Energy (and sponsored in part by Popular Mechanics) is held every 2 years on the National Mall in Washington, D.C. The competition in 2009 saw some surprising entries and innovative solutions to passive design and solar technology. A selection of 20 college teams competed in the fields of architecture and engineering to design, build and operate the most attractive and energy-efficient solar powered home. Winners of the competition gain international recognition for their designs.

Hard-hatted Department of Energy inspectors roamed the Solar Decathalon job sites with check lists, stopping during PM’s stay to ask the workers, “Your PV situation under control? Any code violations I should know about?” The Hokies, like many on the Mall the first day, were still scrambling to get their house rebuilt in a matter of hours after shipping it to DC from Blacksburg, Virginia.

The team had already completed the heart of the system—a responsive pair of sliding panels designed to maximize the house’s efficiency in changing weather conditions. Faculty advisor Bob Schubert walked PM through the five layers that compose the system, which sandwiches each of the rectangular house’s longer north and south sides. On the exterior, a sliding Zahner zinc panel with machine-cut openings provides partial shade against the sun. Next, a layer of diffuse LEDs shines through the zinc screen, giving the house a glowing appearance in twilight. Both of these exterior panels can be set to slide in and out with the weather automatically. The house picks its settings via sensors embedded in its concrete floor. Behind the LED wall, a manually opened sliding door from Fleetwood separates indoors from out; riding in the track next to that is a robust sliding mesh screen. Inside the doors near the galley kitchen, a metallic curtain with a sun-reflecting coating automatically slides over the windows to reflect hot summer sunshine, or it retracts to allow solar heat gain during sunny winter days.

Most impressive about Virginia Tech’s plot on the mall, besides the sliding panel spectacle, was the extensive landscaping the school had done to dress up the site. Rookstool said that the team’s 2002 entry contained “about four potted juniper plants out front,” with little other embellishment. It’s quite a bit more elaborate this time around. “We didn’t want it to be a house sitting in the middle of nothing,” Rookstool said. “Otherwise, it just becomes a box.”

As students shoveled truckloads of gravel between plantings, fifth-year architecture student Travis Rookstool supervised a volunteer making a connection in the house’s passive grey water filtration system. Like its neighbors, Team California, Virginia Tech routes the water draining from the home’s kitchen sink and shower into the garden, where plants purify the waste water for use as irrigation elsewhere in the watery “yard.”

Nearby, a 1,000-gallon tank simulates a geothermal system Virginia Tech designed and built into the house, but was unable to implement due to drilling constraints on the Mall.

Maximum photovoltaic production under optimum conditions: 9-kW per hour.
