energy saving tips

Thanks for the tips. Any idea what tall, fast-growing trees are recommended for suburban homes?

Saving energy in the home is becoming an extremely critical facet in contemporary living. With increasing petrol expenses and the broader ecological problems everyone should do their part to preserve power where possible.

I agree...

Useful tips.

The points about south/west directions will vary based on season and geographical location, so people in different parts of the world may want to adjust based on their local solar irradiation conditions. Better yet, consider all external surfaces when minimizing radiation effects on cooling load.

In parts of California, poplars have been used a lot. They are very fast growing, tall but narrow, and suitable for planting in rows to make a screen that does not take up a lot of space. But be careful about using them if you want to limit their height. They do not cooperate with that at all.
Another lesson learned in CA: Do not even think of using eucalyptus!

Around here they tend to be height limiting they have a tendency to fall over after about 100'

I thought I read a story a year back or so that involved Poplar trees the grew high enough to block the sunlight on a neighbors PV panels.

I believe the court ruling was for the trees to be cut down due to CA law that stated you could not block access to natural resources or such.

Does anyone know if that was a true story or not?

Don't know about any single particular story, but there have been cases where trees (even ones planted before the laws took effect) have been required to be severely pruned back and/or removed when they grew to an interfering height. There have been more cases to date involving scenic views than solar panels, but even without PV involved, just shading your neighbor's garden or backyard is enough to trigger the restrictions.

There are several ways to use energy more efficiently at home and we could save a lot of energy by proper using of electric. Moreover, saving energy especially at home will make a lot of advantages Use energy-saving lightbulbs that can last up to ten times longer than a normal bulb and use significantly less energy.

energy saving tips

electronics, battery chargers and other equipment when not in use. Taken together, these small items can use as much power as your refrigerator. Televisions, cable television boxes, cell phone chargers and other electronics give off more waste heat than you might imagine. Unplug these items or consider purchasing power management devices to eliminate electric consumption entirely when not in use.

Standard disorder, fire emergency lighting quality landslide

Fire emergency lights is the most common one in the fire emergency lighting, emergency for a long time, high brightness, Automatic power-off emergency functions. It is suitable for factories, shops, hotels, schools, units and other public places to prepare for power outages for emergency lighting purposes. General fire emergency lights can be divided into emergency lighting lights and signs.

****After several spot checks data analysis, fire emergency lighting the main problems: First, the use of the disabled battery. Mainly as nickel-cadmium batteries replaced with lead-acid batteries, reducing the number of batteries, and reduce battery rated voltage, which will directly lead to reduced battery life, not enough illumination, power supply mainly the time, but because of its low price, part of the production enterprises to reduce costs, increase profits, using standard shall not use lead-acid batteries; the shell material non-compliance. The vast majority of fire-resistant high-temperature conditions below. Luminaire enclosure shall be non-combustible material, and spot checks to emergency lighting majority of thermoplastic plastic lamp housing and light scattering plate, heat easily deformation melted, the lamp can not provide the expected protection; Third, over-discharge and overcharge protection circuit unqualified. Main part of the production companies to reduce the amount of electronic components and circuit boards inside the fire emergency lighting simplified or over-discharge and overcharge protection circuit is set, resulting in products because there is no protection circuit itself become the source of the fire; Fourth The state of emergency surface brightness failed. Table brightness, fire emergency lighting state of emergency that emergency lighting lighting and evacuation direction indicator on how well qualified or not will be a direct result of the fire emergency lighting can play a retreat for evacuation purposes of guarantee; Fifth protection device failed. Some fuse and protection devices. Fire emergency lighting is switched on for a long time on the main power supply, such as the lines are short-circuit or overload, unprotected device could easily lead to damage of the lamps. Therefore, the fire emergency lighting in the fire can play its due role, should pay close attention.

****In recent years, the fire emergency lights industry ups and downs. Coupled with the current fire emergency light industry threshold is low, and the standard disorderly basically what companies can be flocking, resulting in the industry's chaotic, but also makes a lot of companies are beginning to speculative operations, and speculation in many ways. Some small factories, strict quality control, so holding earn it is a little idea, shoddy, relying on low-quality low-cost competition to earn market share. So has a great impact on the market, also caused by the normal production of enterprises had a certain impact, while the normal production of enterprises is a dilemma because of the behavior of these speculators. These speculators not only undermined the reputation of the domestic fire emergency lighting industry, China's fire emergency lights industry in the international left a bad impression.

***Insiders pointed out that a considerable part of the manufacturer just made some detection of the appearance and the like, in order to check payable to the relevant departments, stock clearance of raw materials in the production process, processing off, off of the assembly process, factory testing off an important part of checks not strict, even a mere formality; Some manufacturers lack the necessary testing equipment, individual or even no testing equipment, especially those small-scale production, just getting started in the business of fire protection products, the enterprise quality consciousness, lack of production technology, management experience, unable to produce a qualified and excellent product; Some manufacturers blind pursuit of economic efficiency, to do everything possible to reduce product cost, just to cheap for the quality of key components, parts, and what is more, to achieve low-cost, deliberately reduce the relevant parts of the technical standards, resulting in poor quality fire emergency lighting into the market. Also occurred with the requirements of the development of the industry, technical conditions change, when the state introduced a new industry technical standards prescribed time, many companies because there is no implementation of the new standards, or continue with the old technology to produce, resulting in today's products replacement of the slow pace suited to market needs.

Taiwan led call for the mainland subsidies needs to return to rational

Taiwan LED industry who said that, the past two years resulting in excess cross-strait LED production capacity, indirectly let initiator of the price rise of appetite, subsidy policy is floating abuse of mainland China, if the future policy of the Chinese government to change, for the entire LED industry order will be there to help, andTaiwan has a core competitiveness, good operating capacity will win.

****Chinese local governments have resorted to a variety of subsidies, especially the purchase of LED epitaxy machine subsidy of RMB10 million (approximately NT $ 4,800 million), but because of technology, personnel, and LED production management experience are not in place LED epitaxial plant machine idle, wasted resources, but fertilizer equipment factory in Europe and the United States.

****The LED upstream epitaxial plant director, said Bank of China had come to visit, referring to mainland China LED related companies, there are 3,000 cases awaiting financing, the Chinese upstream up to 70, 80, but really only three of the large-scale security BDO Runda, downstream packaging factory is several hundred Taiwanese LED plant in China had cooking staff, leaving open a LED packaging factory, indiscriminately grants allow industry to chaos, indirectly endanger Taiwan's industry.

****Unity Opto Chairman Wu Qinghui said that if the mainland Chinese Government to abolish subsidies in machinery and equipment instead of the grant of the application surface, which is a good sign.

****Epistar Shih-Hsien Chang, deputy general manager said the new direction of the mainland, the two sides work together to develop standards through credible institutions test, good quality, cost-competitive grants, this is the LED on consumer and the countries are good a subsidy policy.

****Shih-Hsien Chang and China last year launched a very successful energy-saving TV grant program, for example, was originally in the 32 to 40-inch LED Price sensitivity is high, the LED is difficult to replace CCFL, but from last year, last year the Government of the people to buy.
