Suggest way forward for Malaysia

Malaysia is actually blessed with plenty of natural sources of renewable energy, being located in a tropical region. Solar, wind and hydro energies could be utilised to complement the current fossil fuel power plants for power generation

Renewable energy should be the way to go when seeking for alternatives to fossil fuel power generation. It is also because we need to ensure that the environment is taken into consideration in this matter.
Nuclear power plants are more efficient compare to other plant. New technology developed has made them more reliable and safer. Based of that reason,more and more nations developed nuclear plant in their country.Besides,nuclear power plant can reduce greenhouse gas emissions. This is remain as big issue since most of the people that support nuclear power plant believed that no carbon dioxide is released into the air as no coal or fossil fuels are burnt. Since there are no carbon emissions nuclear power is also considered clean energy source just like solar, wind or geothermal energy.

Another reason why we must consider to develop nuclear power plant is that the initial cost of building nuclear plants is high but the running costs are relatively low. One reason the costs are low is that nuclear plants need only a small amount of uranium to produce a lot of energy. In fact, if the cost of uranium doubled, costs would only be increased by 7%. It is believed that 1 truck of uranium produces as much energy as 1000 trucks of coal.Besides,it also can reduces our dependences on foreign oils and natural gas like biofuels. America, for example imports a lot of oil and natural gas from other countries. The price of these products is not fixed and change very quickly. If the price increases quickly, consumers have to pay more for their electricity (which they may not be able to afford). All newly built nuclear power plants need to satisfy maximum safety standards, and the newest nuclear reactor designs really ensure maximum safety by applying the concept of the negative feedback loop, which ensures that as the nuclear reactor's power output increases, it becomes more and more harder to squeeze any more power out of it, meaning that nuclear chain reaction that could lead to nuclear reactor explosion is almost impossible to happen. Though this design is not totally foolproof it is much safer compared to the older designs.

Nuclear power plants do not need fossil fuels to produce electricity, and this means that they do not release harmful carbon emissions that contribute to pollution and climate change problem.In order to properly operate nuclear power plants require nuclear fuel. Nuclear fuel mostly used in nuclear power plants in uranium though some nuclear power plants also use plutonium. Uranium is plentiful in United States, and building more nuclear power plants would therefore contribute to better energy independence as there would be reduced need for importing expensive foreign fuels.Nuclear power plants operate very efficiently and reliably. Their efficiency is comparable to coal power plants, and once they are built they are extremely reliable given that there's enough uranium to feed them, and as already said there is plenty of uranium in United States.

The main disadvantage of nuclear power plants is no doubt nuclear radioactive waste that has lifespan of more than 5000 years so more new nuclear power plants will mean more radioactive waste, and current nuclear waste storage options definitely do not ensure totally safe storage for the next 5000 years or so. Another challenge is how to protect a nuclear power plant from earthquakes, which can damage reactor containment structures and expose the nation to the risk of radiation leaks. Areas around Janda Baik and Bentong, towns in the Malaysian state of Pahang, have experienced minor quakes twice in the past few years. Volcanic eruptions in nearby Indonesia have also shaken some areas, although Malaysia is not located in the Pacific "ring of fire" that is home to most of the world's volcanoes. Malaysia cannot afford to risk building a nuclear plant in an area that could be vulnerable to a volcano or earthquake; the consequences would be too devastating.

Proponents of nuclear power point to the current energy situation in Malaysia as evidence that new energy sources must be developed. Government officials believe that Malaysia's current energy sources will not be sustainable beyond 2020, and that the depletion of the nation's fossil-fuel resources is a threat to national security.

Analysts predict that escalating global oil prices will force Malaysia to become a net oil importer in the years to come. Malaysia uses oil mainly in the transportation sector, and relies on natural gas and coal (along with hydropower) to generate electricity. However, government officials have expressed concern that the cost of coal and gas is likely to soar in the coming decades, as supply fails to keep up with demand. Malaysia's coal imports, which held steady for many years, have grown rapidly in the past two years. Natural gas is currently the largest energy source for the country, but national gas fields may be depleted by 2027, which would leave the country unable to meet petrochemical industry demand and commitments for exports of liquefied natural gas.

Because of these gathering storms, there is no doubt that Malaysia urgently needs new sources of energy to assuage its future energy demands, and nuclear energy seems a very attractive alternative -- particularly since the neighboring countries of Vietnam and Thailand have already announced plans to bring their first nuclear plants online by 2020, and Indonesia intends to construct a plant on Java Island by 2015. Nevertheless, for Malaysia, the prudent management of current energy resources -- to ensure that they are sustainable over the long term -- deserves serious consideration as an alternative to nuclear energy.And the other futuer we need the nuclear power plan to source the energy for our country.
