According to energy consumption map, about 38% energy resources from entire world have been used to generate electricity. This electricity comes from hydro, biomass, geothermal, wind, solar, nuclear, coal and natural gases. The other sources such as petroleum and natural gases go to industrial, commercial, residential, light-duty vehicle, freight and air craft. Nuclear only used for generating electricity which is about 8.13% from total portion of energy resources. The energy consumption in form of transportation, industry, agriculture, domestic and food the day by day is keep increasing according to The British Royal Commission on Environmental Pollution. With the increasing of demand in electricity, the minimum demand (base load) is about 10,258 MW. The latest peak demand is about 15037 MW. How do meet the base load 10,258 MW demand? This base load needs to be supplied by coal, gas and hydro.
All this conventional technologies produce the CO2 green house gases by process of combustion. This green house gases clearly is not good for our world. These green gases will make the effect of the earth’s surface warming because it is preventing the infrared radiation from passes through the atmosphere and lost in space. The average concentration of CO2 today is about 388.15 parts per million (ppm). We must remember that, the breakaway emission of CO2 is 450 ppm!! With the current population growth, in year 2025, the number of 450 ppm will be achieved. We cannot live anymore when we achieved that number. We are getting closer and closer.
Increase in carbon concentration is related with the increase in temperature. When the temperature goes up, the temperature at North Atlantic and the Southern Ocean will also goes up. Again, we must remember that this place is the coolest place in our world. This place is the important part of thermahaline circle or The Great Conveyor Belt. What will happen if the heart of this Great Conveyor Belt is affected? We must highlight that, all the phenomenon, the climate change in this world is related with this Great Conveyor Belt. The hot wind is circulated around the world followed this conveyor path and the hot wind is cooled at the North Atlantic and Southern Ocean. We cannot let the heart of Great Conveyor Belt be effected by the rise of temperature. So we have to turn to green energy.
The Green House effect is seriously affecting all the living things in the world. We can't wait for it to get to the critical state then only we will start to work on it. The population will grow in time and steps need to be taken to make sure our future generation continues to live on Earth. Everything have to be green especially the generators, industries and definitely the vehicles we are using right now. Trade in all the old, black and all kinds of smoke producing cars and get a new one!

The world is going green currently.Nuclear reactor is recognized as the greenest alternative as the most efficient power generating.Electric-powered car is the greenest transportation.
ReplyDeleteOne more thing the engineers as well the societies should pay attention to. Green buildings. Buildings are responsible for 40% of the world's greenhouse gas emission, and 40% of the global's solid waste generation.12% of the world's water is used by buildings. The air quality in buildings contains 5 times pollutant more than the outdoor.And buildings utilize 1/3 of the world's resources. Megacities generate 80% of CO2 emissions. Analysis said that in 2050,70% of thw world population will live in megacities. Does these statistics enough to get the attention needed? For me, they do. In green building business, the World Green Building Council had already came out with Green Building Index. Malaysia is a member and currently taking the first step in green buildings environment.
The green buildings are not only use less energy but also able to produced their own. The cutting edge of the green buildings design are skyscappers tipped with wind turbines,windows embedded with photovoltaic crystals turning sunlight into electricity, systems that collect and reuse rain water, intelligent heating,cooling and lighting technology.
One good example of green building is the 190-m Turning Torso in Malmo, Sweden, built with LEDs flooding the corridors with symmetrical white light. These LED achieve 80% energy savings.
Green environment produces cool buildings though.
Nuclear power little greenhouse gas attached to it,for an example when mining uranium ore, refining and enriching fuel, building the plant, and operating it are included. A big 1,250 megawatt plant produces the equivalent of 250,000 tons of carbon dioxide a year during its lifespan.But that's still much less than coal-fired power plants and natural-gas turbines. It is so much better than solar power and small-scale hydro projects.Therefore nuclear energy in by all means is the greenest energy found currently!

I am also really concerned about the great conveyor belt. Before I was exposed to this knowledge, I thought that there was still lots of time to save the earth... It wasn't true however. Renewable energy and nuclear energy are our best bet at times like these. We should also do our part on saving the environment and should not wait for the government to take action. Power to the people!!!

nice article..i hope when there are a lot of countries start using nuclear energy,we can reduce the temperature and co2 emission.I hope we will never achieve the 450ppm breakaway emission.Nuclear energy is the greenest enegy at his time.

In my whole life it is my first time to listen the phrase Great Conveyor Belt which means the starting of a hot temperature and the flow and lastly the location where it becomes cold.Thanks to the speakers in the Green Talk whom makes me understand about the nuclear.And also a big thanks to Dr Syukri who is the organizer.Yes!Malaysia should now buld a NPP in our country.Its because its just clear that the Chenobyl thing wont be repeat again our world..Thanks to the inventors.

Hey there. I agree that we have to turn to green energy and stop depending on our natural resources because they will not last any longer. Besides CO2, greenhouses effects and melting of the polar caps, there is also acid rain. Acid rain is caused by coal and oil have which have sulfur impurities. Acid rain's effects are destructive and long lasting.
ReplyDeleteNatural resources depletion is a growing problem. We should stop depending on them.
Thank you.

The fact that you stated about the carbon dioxide concentration is crucial. Everyone should know that if we do not start an effort to save the Earth from this moment, the sooner our dear planet is coming to an end. By then, our next generation will not get to see a beautiful world like what we are seeing now. Therefore, for the sake of our children and every generations that are about to come, we should start implementing the use of green energy.

ok, good summary indeed.. but something i just want to know.. because I never going to any nuclear power plant, I would like to ask u is the NPP using turbine??
ReplyDeleteYes..the concept still the same with power plant in our country.Heat generated will rotate turbine to generate electricity...NPP make use of nuclear reactor to generate heat,otherwise the conventional power plant uses coal/natural gases to produce heat.Some power plant make use hydro to move the turbine.

ReplyDeletewith both global warming and the depletion of fossil fuel crisis, we seriously need to consider nuclear because nuclear emits low co2 in electricity generation and the source of uranium can actually last for a couple hundreds of years... but i think further research need to be funded in managing the radiation mines waste like the one in Rum Jungle in Australia...
