Every country, every scientist now is searching and looking for the most efficient, most long-lasting, most environmental friendly, cheapest way to produce alternative energy.
Options are out there available, such as, nuclear power, biomass, wind generator, solar power. To be able to enjoy these alternative energies, there must be infrastructure to run them such as nuclear reactors, wind turbines(on sea), solar panels. These infrastructures comes in billions which developing countries find it difficult to afford. Malaysia, however, has the potential and glad to hear that Malaysia is planning to build its 1st nuclear reactor in 10-yrs time. Apart from that, I think solar power is the next energy that Malaysia has in abundance, and we should not waste it.
About cars. We can now see hybrid cars coming into Malaysia, however it is much more expensive than the ordinary cars. :( I predict the next generation of cars would be running on batteries with solar panels on its body. Then, it will evolve to run on hydrogen gas. It has been established that hydrogen can be a fuel in a car and there are a few "concept" cars in US running on them. So what will be the fuel for Hydrogen-powered cars? It is H2O, water. Haha... And guess what, India has already invented few models of cars that run on Air, yes, Air, - pressurised air. No fuel, No emission, no pollution. So, lets wait and how vehicles evolve in the next 10-20 years.
Let's share some information of yours on alternative energies and ways to save energy. Maybe using a Bicycle in not a bad idea after all. :)
