Urgent Evoke - no power credit needed;just input.

Finding ideas on sustainable energy has not being easy as I intially thought,it has been tough;not in the sense that there are no ideas out there.

There are many ideas,however,I find that most these ideas are one dimensional in the sense that they are focused on one type of technology -microbial fuel;hydro;solar etc.All these are credible concepts(some better than others).But since the only thing that is constant in life is change.

I think one has to consider whether these technologies take into account the some of the factors that could possibly influence change within a particular context:

• location:this will determine the type of technology appropriate for the area [topography considerations].
• electricity usage: on avarage what do people use electricity on;how much of it.
• wind:is it strong enough?;etc
• solar: is there enough radiation to generate electricty for the"area" ; storm-dust.
• hydropower system: is the water source perenial/or not; strong enough current ?
• resource availbilty:what else does the area have that can give a certain technology an advantage over others.
• cost:socio-economic status of the region
• etc[I don't think I have exhausted factors that might influence the appropriate off the grid technology]

Some of these things change with seasons - does the technology cater for these changes ?

These factors will determine whether such a technology is actually sustainable,and I find that a hybrid solution[a combination of one or more of these technologies] is the "best solution" since it will anticipate changes within the particular context;I have yet to find someone who has a hybrid solution or am I looking in the wrong places ;asking the wrong questions- please help.

Thanks in advance
