alternative energy


It is for an energy assignment in science about alternative energy. You know the usual stuff solar power wind power all that stuff. what do you have to think about when you’re thinking about choosing an alternative energy source

  1. What are some new and potentially useful alternative energy sources?

    I’m looking for something besides the usual fuel cells, solar collectors, photovoltaic cells, waste-to-energy, hydro-electric, etc. I think I read somewhere about harnessing body heat for energy. Anyone know anything about that or can give me some links on that or on other developing technologies for alternative sources of energy away from gasoline and natural gas? Wind mills is included in the “etc.”....

  2. What is the cheapest alternative energy to implement and how does it compare to existing conventional energy?

    What are current energy prices of alternative and conventional techniques?...

  3. What is the purpose of looking into alternative energy sources?

    What is the purpose of looking into alternative energy sources?...

    mainly local environmental impact.
    eg. daming a river for a hydro turbine is no loger considered environmental as it damages the local environment.
    As microhydro turbines don’t as they only divert part of the river a bit.

    The embodied energy is also important factor when considering what alternative energy is going to used.
    For example solar hot water heaters have an energy payback of about 1 year.
    Solar Panels have an energy payback of about 6-8 years.
    As the silicon is a rare metal when requiring to build them.
    Then it would be the logical step to first use a solar hot water system before putting solar cells up on your roof.

    Same with wind power you also need to consider viability of the energy source at that location….
    If there is not enough wind or too much turbulence.
    This can effect what energy source is considered most viable at that location.

    First of all, take the availability and renewability of the source into consideration. If it’s both renewable and freely available, it’s OK. Also consider: “Will it provide a cleaner means of energy?” or “Will it be as efficient or more efficient as those sources of energy today?”

    Then, consider the pros and cons; the advantages and risks. For example, a certain alternative energy source could be more abundant, but it could be as expensive or more compared to today’s energy sources.

    Last but not the least, consider the cost. Can every average person afford it?
