  3. Solar energy


    Clean
    Inexhaustible



    Can’t work at night
    Works less efficiently on cloudy days

    Wind energy


    Nonpolluting
    Freeish
    No waste



    Sometimes weak wind
    Sometimes too strong wind
    Many times can’t create electricity

    Water energy


    Microhydro power
    Pretty
    Creates electricity by water

    Erosion increases
    Floods
    Habitats are damaged

    Wood energy
    Renewable energy because wood can grow back


    gases and small particles are released
    Habitats are destroyed when we cut down trees

  4. A disadvantage of using Wind Energy is that, It's not always Windy. An Advantage of using Wind Energy that when it's Windy It helps a lot.

  5. An advantage to solar energy is its clean, a disadvantage is it doesn't work at night.

  6. A advantage would be, that when we have a lot of wind in would . And also a disadvantage would be for using wind energy is that it is not always windy.

  7. it cost money and dosent produce a lot of energy it cost a lot to make the thingys

  8. its good for nature

  9. The advantage is that it is cleaner for the environment, and the disadvantage that it doesn't work

  10. The advantages of wind energy is that if it's windy you have a lot but a disadvantage is if it's not windy your gonna have barely any.

  11. Advantages of each is they are all cleaner for the environment,They all are also very renewable.The disadvantages of them is that they don't produce as much as fossil fuels.Also there could be a bad day out then it might not produce enough sun because it could be a cloudy day or sometimes the wind might be very calm.

  12. The advantage of wind energy is that if it's windy you have a lot of disadvantage is if it's not windy you not gonna have much wind energy.

  13. The advantage of Wind Energy is that when it's Windy you will have a lot of Energy and the disadvantages are if you don't have Wind you will not have any Energy.

  15. One of the adv is clean air

  16. If it's windy it could charge power for the windmill or it's could knock down power lines.

  18. I say the correct answer.

  19. Solar Energy:
    For us to MASS-PRODUCE it, meaning our reliance on it is like more than 50% of the whole world population, we would need to clear off large areas of land to put the solar panels there.
    Advantage- Eco-friendly
    Wind Energy:
    Same with solar power, if we use it too much, then it can affect weather systems, and affect birds migratory system, because they'll be chopped up if we put our wind turbines in their migratory path...
    Advantage- Cheap, eco-friendly
    Hydro:
    Destroys water ways, thus weakens our eco-system because the species of some places need the water from the river, but once that river is blocked, then they have no water.
    Ecofriendly...

  20. The advantages of using solar energy, wind energy, and hydroelectric, are that without using unnatural gas we could save global warming. (no pollution)

  22. The advantage is the wind energy gives off a lot, the disadvantage is if you dont got that stuff
    no energy fo' you.

  29. bad thigs about solar energy are the energy bill will be too high and to expensive.

    1. it is a disadvantege because it only works when the sun is out and april u would have no power

  30. It is a advantage because it helps earth but the disadvantage are when it is cloudy or night time it dose not work.

  32. The only disadvantages of all three of them are the cost. They're very expensive. Solar and wind are less than 20 percent efficient, so the output is not very dense. With time and innovation, I believe those can be rectified. The advantages of all of them is that they are infinite, renewable, reusable, and low-maintenance. That wind will blow, water will flow, and sun will shine are all guaranteed.

  37. solar energy can be used as electricity but solar panels are hard to make

  38. They are cleaner and better but they are way more expensive.

  39. Solar energy is great because it is healthy for the environment and renewable but solar energy does not work at night and the battery which stores the energy is disposed of not properly can cause pollution.

  46. The advantages are its cleaner and i think it cost less in the long run !!!!!!!!! The disadvantages are that it doesn't work when its not sunny or wind or when its cloudy and night time ! :D

  47. The advantages is that they are natural resources of energy. However a disadvantage is that you don't know when it will start or stop.

  48. Solar energy could give you sunburn! ouchie! But it's hot! yay! And the other stuff.....I don't know.
