malaysian energy

Malaysian can benefit from the sun energy. The country had moved one step closer to support the sustainable green energy by producing feed-in opportunities for the average consumers and small scale entrepreneurs. That mean a household can install solar panels and harvest the sun power and they can sell the electricity to the National Electricity Company, TNB.

You may like to get more information on how to build solar panel from Green DIY .

This is how it works.

1. A new law, the renewable energy act 2011, enables the national energy company TNB to buy the produced electricity at a special rate.

2. A body called SEDA, sustainable malaysian energy development authority was set up as the go-between the producers of the electricity and the TNB. Anybody who wants to produce and sell the energy to TNB has to apply to SEDA . The FiA (Feed in approval) will be given when SEDA is satisfied with the quality of the electricity produced.

3. Upon approval, the FiAH -feed in approval holder will be supplied with the feed-in capability, that mean the energy produced will be allowed to be linked.

Photo cells convert the sun energy directly into electricity. So far the quota for the application have been taken for the next 5 years. For individual applicants, another 4.8MW was available. Even if the TNB does not buy the energy, it does make financial sense to install the unit. For a hot and long daylight, malaysian can rely on the energy from the sun.

The malaysian energy policy is still considered by many as rather unfocused. The country is endowed by plenty of natural gas, but the domestic usage is rather low, the usage of gas for vehicle is limited to taxis in the capital.

recycling rainwater

There are two basic issues that rainwater recycling can address.

1. reduction of flash flood

2. reduction of the dependent on water distribution.

With more urban development, the natural water retention capability of ponds, soil absorption an natural plantation are greatly reduces. As such the rain water will tend fill up the drains and rivers at as faster rate. With the rain catchment mechanism, some of the water will be retained.

The other main reason is the reduction of the strain on the water supply. It may not seem very much, but a reduction of 10% from the supply will amount to millions of liters.

At the current cost level, the payback for the investment is not attractive. It takes 10 to 20 years to get back what you had invested. However, beside the commercial reasons, the water recycling can offer the following advantages:

a. The rain water is suitable for the secondary usage, such as flushing toilets, washing machines and watering the plants. The water is soft and does not contain chlorine. It can be used to clean floor or surfaces without leaving behind scales or stain.

b. It can help to ease the dwindling supply of water. With increase in population and the increase of urban residents, the demand for piped water is on the rise. The situation is made worst by the pollution of the rivers and natural water resources.

c. It can reduce your water bill. It is expected that the price of piped water will increase, so will be the cost of the recycling system.

The system is available for installation of the recycling system.
