This talk is very interesting because it provides us a new view which
is using energy effectively to reduce energy consumption. First and
foremost, Amory Lovins takes oil consumption of America for example to state
changing the way of energy usage is better for country security, environmental
management and public health. For electricity, saving energy becomes more and
more important, he mentions that it would save about 1.4 trillion dollar
present value after 4 decades by integrated design. Moreover, renewable
energy is too expensive and unreliable, but efficient usage of
energy has low cost.
I have some ideas from this talk. I think
it is more important to find some ways to use energy more effective
rather than finding other new energy to replace the present
energy. Of course, renewable energy is useful for environment, but
as mentioned, it costs much and often rely on weather, so people should pay
more attention on how to use energy.
