Comparison Of Fossil Fuel and Nuclear Power


There are lots of resources in generating energy to power up our daily live. The increase in the demand of energy has put a lots of challenges to fulfill the required needs in the century. Lots of consideration and comparison has been done to gain knowledge in generating energy. The table below are premised on the assumption facilities run with reasonable attention to environmental protection so far as routine operation and concern of waste management.

** Question has been raise about the effect of krypton- 85from extensive reprocessing necessary for a breeder reactor system  on  cloud formation and hence potential climate change. However krypton- 85 can be removed from exhaust gases by cyrogenic cooling.

Malaysia's Options for Power (Part 4)

Biomass

Issues
  • Small scale and intermittent - not enough to materially provide security of supply (not constant)
  • Economically unattractive
  • Wind - we live in a low wind speed region
  • Biomass - fuel supply and transport issue
Possible Solutions
  • Systematic promotion with proper policy and incentives for viability from government
  • Focus on developing mini-hydro, solar, biomass and biogas
  • Need feed-in tariff

Biomass helps to reduce landfills hills by reprocessing the waste to become biofuel. This biofuels will be burned to heat water and generate electricity, yeps the typical process of power generation. The problem with burning carbon is the product will be carbon dioxide gas. Don't forget the smokes too.

During our Renewable Energy lecture, we learnt that biomass suppliers (mostly palm plantation companies) prefer to sell their product to outsiders instead of generating their own power plant. It is more profitable of course. Same applies to our petroleum, remember?

To conclude things up, all I can say is, we have to sacrifice something in order to gain something unless we want to go back to the old days. I need my smartphone. I need my computer and of course I want to travel around the globe with ease. Think about it.
