I think this question is not ONLY based on safety and environmental concern, but on a "need-basis". Lets have a look at this issue from a different perspective:
1) Power generated from Hydrocarbon (HC) or HC derived source (diesel power plants, gas power plants, coal power plants) will not be running forever, as HC source is finite, and fast depleting. Malaysia is expected to be a net oil importer by 2015. (subjected to discovery of new oil fields). Signs of we are running fast on fossil fuels is oil companies are chasing after small oil fields (lesser than 1.6 billion barrels of oil reserve in a given oil field). These oil fields were never even being considered to be drilled as recent as a decade ago.
2) Alternative energy: Solar is at its infancy stage, and tremendous leap has to be made to enhance photovoltaic potential to its maximum. A good medium sized solar power plant in malacca is operational by 2015, supplying only 200MW. This is barely enough to supply power to a medium sized city with approx. 200,000 households. Lets not even argue about wind power and geothermal power plants as Malaysia has no access to strong winds or even has readily available geothermally active areas.
3) Yes, hydro-electric dams can be an answer, but dams like bakun or any large scale hydro electric power plants need rather large rivers. In malaysia, we have rajang in sarawak, and kinabatangan in sabah. No rivers in peninsula malaysia have the capacity as these two rivers. The power can be transferred via undersea cable, but the cost will be collossal. This is the main reason why no undersea cable was laid from bakun to peninsula Malaysia, and Bakun is practically forced to sell power to Sarawak. Bakun had to sink an area of singapore island to retain enough water to generate 2400MW. The qustion is, can we risk sacrificing so much of of biodiversity in the name of generating power? the math is simple: If malaysia needs 20,000MW energy by 2020, and assuming 100% is coming from hydroelectric power, we need to sink a total area equivalent the size of 8.3 times the size of Singapore island. That is 5831 sq. kilometers.
4) We are talking ONLY about generating power for homes,factories and commercial buildings at this point. But what about aircrafts, ships, electric trains, defence mobility,etc etc? Current hybrid and electric vehicles (EV) are suitable only for light vehicles, such as cars and 4x4. Still then, full EV needs to be plugged into conventional power source to be charged. Imagine 50 years from now, if every household in malaysia has 2 EV's, as is the case today with average 2 cars per family, the power demand would be EXTREMELY HIGH! Where do we generate that kind of power? For the record, we have currently 10 million vehicles on Malaysian roads, with annual increase of 5% in total industry volume (TIV).
5) We are still far off from energy source such as Hydrogen nuclear fusion (conventional nuclear power in todays world is generated from fission principal, using Uranium). Hydrogen power would be the holy grail of ending the impending energy crisis, But the technology is still decades, maybe even 1 or 2 centuries away. Hydrogen power is the equivalent of today's hydrocarbon power, which can be used to generate power by power plants, aviation, shipping, road bound vehicles and all. But as I said, it is still years away before it becomes a feasible alternative to hydrocarbon fuel.
Till we reach a stage where we can say we have discovered a way to entirely replace fossil fuel, (be it hydrogen fusion or any other source of energy), we need to find ways to reduce dependability on fossil fuel, and embrace so-called "risky" technology. Yes, I do agree WE NEED nuclear energy. The benefits and risks of having nuclear energy has been deeply debated by the readers on this page, but our fear is due to our lack of knowledge in this field. All we need to do is enrich our knowledge in nuclear power and its related technology, and most importantly, treat the power with respect. Many may disagree with this statement I'm about to make, but like it or not, there is no other viable energy source to nuclear energy at this point, and we will have to embrace it at one point, wheter we like it or not.
Before signing off, I would like to share a small bit of automobile history I read some time back.
When cars were invented more than 120 years ago, there were many sceptics about this new invention. Most people were asking how are they going to feel safe while driving knowing they are seated barely a feet above a tank storing gallons of easily combustible fuel? An aristrocat even said automobiles are just a "passing fad", and that horse carriages would still prevail after the automobile novelty had worn off.
Today, the world is still driving with fuel tanks barely 3 feet behind them, and horse steak is a french delicacy. ;-))
