1. why isn't solar energy usually the only power source for a region? 2. wind farms can also be used for which other purposes? 3. using hydro energy often requires that people build what? 4. what type of dangerous waste is produced by nuclear power plants 5. what is biomass? 6. what is carbon capture and storage? 7. what is energy reduction? 8. list at least two ways in which people can conserve energy. 9. how do smart grids use timing to determine electricity prices?

1. Every region doesnt get the same amount of sunlight as the rest due to whether or location an example would be that a region with alot of rain could have clouds that wouldnt let the solar panels to absorb as much sunlight as a more dry and sunny place 
2 wind farms can be used to store energy for a power outage and a way to lower the cost of electricity to a farmer 
3 using hydro energy requires people to build a dam that pours the water over a mill that rotates and stores energy from it 
4 a type of waste created by nuclear power plants would be daily uses that have radiation such as plastic containers ,gloves , disposable overalls, boots or just plain radioactive waste.
5 would be the total mass of organisms in a given area or volume 
6 is a process to further limit carbon dioxide emissions from burning coal
7 is basically the means to tap into energy savings that over time become an asset 
8 turning down the water heater thermostat and turning off lights when not in use can save energy 
9 smart grids use timing grid to determine how long you use electricity for and for how much you used
