Let's think about it=)

Hye there ^___^

Finally i  have done my pjbl task which consist of debate and seminar..well done to all my course mate and myself. But here there are two centre guided questions  need to  answer. So, let check it out=)

1. How life without energy????
2. Can Nuclear Energy become a dominant energy in Malaysia????


Here some answer for question 1 that i have 'google' from internet: 



... living in the dark, unable to keep warm, turn on a light or boil a kettle



... relying on burning wood or dung to cook, and having to breathe in potentially fatal smoke


... your child living under the shadow of disease because they couldn't have a vital vaccine, due to a lack of refrigeration


Education without energy?

Without energy, people's ability to get a decent education is severely affected
Education is acknowledged as a crucial factor in helping people escape from poverty. In communities without energy children are often forced out of school to help collect cooking materials or earn money.
When they do go to school it has to be in daylight, which restricts their hours especially as many children walk for hours to get there. When they arrive home needing to do their schoolwork, they have no light to study and all that greets them is darkness. Or they have to rely on kerosene to provide precious light, which is both expensive and dangerous; if a lamp is knocked over it can cause serious burns.
Computers, radio or TV lessons are important tools in the modern education. A lack of electricity restricts the opportunity for children to further their education. And teachers don't want to work in communities where there are no lights, little equipment, no TVs, computers or life after dark.

Livelihoods without energy?

Without energy people's ability to earn a living is also severely affected. As with education, life without modern energy is also denying people knowledge. Without electricity there is no access to radios, computers or the internet, this means no access to vital information such as radio programmes about farming techniques, flood warnings or local news.
Lack of energy means people struggle to start a simple business like; sewing, welding, or battery recharging which could be their way permanently out of poverty.

Health without energy?

Without clean, modern energy people's health can be severely affected
One of the greatest energy needs across the world is for cooking, something which we take for granted. Without a decent energy supply, people are forced to rely on biomass - wood or animal dung - for cooking.
Women and children can spend hours every day searching for increasingly scarce resources. They are at risk from wild animals and in some countries, rape. But it doesn't end there, once they start burning biomass, the thick acrid smoke cause's serious lung diseases turning kitchens into death traps. Children and their mothers are most at risk, choking, retching and gasping to get air to their lungs which are being attacked and destroyed by smoke.
More people die from smoke inhalation than malaria. According to the World Health Organisation's , diseases associated with indoor air pollution claim 1.6 million lives every year - that's one person every 20 seconds.
This is sample answer for question 2 ;


Nuclear Energy can be a dominant energy in Malaysia because Malaysia will run out of Petroleum which is a dominant source of energy for now. We should replace the petroleum with other high potential of energy source. And the answer is NUCLEAR ENERGY. This is because Nuclear Energy have a lot of advantages. This is the list of advantages of nuclear energy compare to other energy. 

  • Nuclear power plants are more efficient than ever before. New technology has made them more reliable (they break down less often) and safer. People for nuclear power argue that this is evidenced by more and more nations (such as China) building nuclear power plants.
  • Reduce greenhouse gas emissions. This is a contentious issue. Proponents of nuclear power argue that, as no coal or fossil fuels are burnt, no carbon dioxide is released into the air. However, uranium has to be mined and transported to the nuclear plant. Both these activities require burning of fuels, so carbon dioxide is released. Also, producing nuclear fuel from the uranium requires a lot of energy, which also contributes to the emission of greenhouse gases.
  • Although the initial cost of building nuclear plants is high, 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%. 1 truck of uranium produces as much energy as 1000 trucks of coal!
  • Reduces dependence on foreign oils and natural gas (like biofuels). America, for instance, imports a lot of oil and natural gas from other countries. The price of these products is volatile, 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). Building more nuclear power plants means that Americans will not be susceptible to price rises in oil and gas. 
  • Nuclear wastes can be safely stored underground.

So,what are you think???
Till then,salam.
