Kat | Matt |
Matthew: I heard that you work at an renewable energy company. Can you tell me what kind of company it is?
Kat: My company is a wind energy company but there's a lot of other options.
Matthew: What are the other options and what are the pros and cons of each option?
Kat: Well let's start off with wind. Wind energy is great. It doesn't take away a lot of space. You can have one wind turbine in a very small area but on the other hand you really need some strong wind to have a good output. Then you have solar energy. Solar energy is great but you also need a very good location and solar exposure is normally just a couple of hours a day so you need a very big solar panel so it takes away a lot of space. Then we have the option of geothermal energy which is great but once again depends on where you live. Very few areas have what it takes to have a productive geothermal system and it's very expensive. There's a lot of drilling involved. Then another option is bio-energy which is where you actually take animal waste and use that to make energy. I think it's one of the better ones but once again the set up is highly expensive. Then a last option would be hydro-energy. Hydro-energy I think is best in very large set ups, government-run or run by large electricity companies. It's very expensive to set up but once it's set up, it's a very, very productive way of making energy.

on the other hand
But on the other hand you really need some strong wind to have a good output.

- It's nice, but on the other hand it's expensive.
- On one hand it's interesting, but on the other hand it's noisy,
crowded and dirty.

We have the option of geothermal energy
