CH EN 6158 HW 6 PROBLEM 6.4 The International Energy Agency in 2010 proposed recommended strategies for countering global warming by reducing global CO 2 emissions. They list several strategies including CCS, renewables, nuclear, power generation efficiency and fuel switching, end-use fuel switching, and end-use fuel and electricity efficiency (see Figure 1). Following IEAs BLUE Map scenario of reducing current global CO 2 emissions by 50% by 2050 increased nuclear power will need to account for 3 Gt CO 2 reduction. [1] This paper will discuss the feasibility of the estimated increased nuclear power capacity to account for the needed according to the 2010 BLUE Map scenario. Figure 1: Key technologies for reducing CO 2 emissions under the BLUE Map scenario [1] In order to achieve the desired CO 2 reduction from nuclear the BLUE Map scenario targets an increase of nuclear capacity to 1,200 GW by 2050 providing around 24% of global electricity (up from 370 GW providing 14% of electricity as of 2010). [2] Under the BLUE Map scenario nuclear power provides a major contribution (19%) to reducing CO 2 emissions (see Figure 2). Nuclear power generation has stalled over the last couple decades and has leveled off at the current level as seen in Figure 3. Several challenges are present if nuclear power is to provide the desired CO 2 reductions include: current and next-generation technology, commitment to nuclear energy, financing, increased human resources and industrial capacity, management and disposal of radioactive wastes, and safeguards on nuclear technology and materials.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
