solar energy disadvantages
What are the disadvantages of hydropower?
I also need the disadvantages of solar, wind, geothermal, tidal, biomass and hydrogen energy
You are basically talking to summarize several whole branches of research services energy public so far and research organizations have already spent millions of man hours. So. Start reading! Here's the advantage: Hydropower is generally based on the dams. Dams look great, but actually have an enormous environmental impact. Even the most carefully planned dam will create a lake above it and reduce water flow beneath it. Find out what is happening in China with its large prey. The water leaving the dam is "thirsty" – Depletion of sediments by the dam, is now extra-erosive. The river eats away at the riverbank, soil washing into the ocean and depleting agricultural lands. Wind and solar power – the capital investment remains expensive. Geothermal – you have to be near a source … Hydrogen in Iceland is not a source of energy. Where does hydrogen come from? You can not remove … you have to get that water. But that costs more energy than you get from burning it. Thus actually, we should see more as a hydrogen battery, "a source of energy. Also keep in mind that water is a greenhouse gas gases. I can not think of a disadvantage of biomass energy. Perhaps because there is less mass in question would have to spend all this? Moreover, if you are generating biomass for the explicit purpose of making energy, you are no longer carbon neutral. Methane also is not very good for envronment. Copy and paste what I wrote not on paper. Each of these things suggests more research and reading. Please make sure you understand what I said and why I said, because that's why I help people.
