Solar Energy

Review by Na'Daisa

Energy makes everything in the universe happen.  Lights in cities use energy.  Energy comes from energy sources.  The most common energy sources are oil, coal and natural gas; which are known as fossil fuels.  Solar energy is energy from the sun.

We use a staggering amount of energy.  As the population grows, we will need more energy.

Nuclear reactions happen in the center of the sun.  The reactions give out huge amounts of energy.  It is given out into space in the form of radiation.  The main types are light and heat.  Heat and light from the sun travel as rays.  Heat rays from the sun that hit Earth's surface makes the surface warm.  The heating effect is also greater in summer.  The warm surface of the Earth heats the air above it.  This heat makes the air swirl around, which creates wind and rains.

  1. With the growing population, we certainly need to rely on another form of energy that is not fossil fuels, because once we run out, they cannot be replenished. I believe that solar energy is the most reliable form of energy, we just need to figure out how to store it so it can be used when the sun is not out.

  2. Very good, but I am not sure what kind of nuclear reactions happen in the center of the sun. Looks like I will be reading this book to find out. -Akiera

  5. We do use a staggering amount of energy Na'Dasia! Solar energy is one response to this problem. We can also commit to using less energy. Maybe we can turn off the lights in the library on sunny days to do our part! <3, Mrs. Haas
