We can build a hydro-electrical power station or use solar batteries(?).We could also save electricity and use less fossil fuels.
(All this questions are so HARD!!!!)

Science Lesson 2
Please choose one of the questions below and post your thoughts.
(1) In SAM recently, Wei Zhi wrote about energy conversions and posed the following question:
As we use fossil fuels - natural gas and oil in Singapore to convert chemical potential energy into electrical energy, what are we going to do as these natural resources are running out?
(2) Most of you talked about the chemical potential energy we store from food. You also talked about how we convert this stored energy into kinetic energy through moving aound.
Imagine you are all running around playing football (yes girls included).
Can you think of how we could make better use of this converted kinetic energy while we are running around?
Remember that answers are to make use of your knowledge of concept of conversions of energy.
Label title:
(1) Alternative Source of Electrical Energy or
(2) Alternative Use of Kinetic Energy
