| Is there a good book or website that would explain to a beginner all the
components of alternative energy, like where or what kind of batteries are
used, explanation of units involved and how many you can expect to get or
typical amounts needed of energy for typical appliances or where to look for
that number, or whether you need to use different types of appliances?
Like explaining how many Watts or would it be kilowatts needed in a typical
day? Also explain generators. I've been reading Nick Pine's messages on
various forums for years and wished I knew what he was talking about! I've
also had an interest in these things. I've studied physics before but
forgot much of these things and never knew how to apply the knowledge. Also
would get the Real Goods catalogues in the mail many years ago for awhile;
not sure why they came to my house.

Start with the Electricity 101 articles in
http://www.rebelwolf.com/essn.html
Renewable energy projects use Deep Cycle batteries, designed for heavy,
repeated discharge, charge cycles. Starting batteries can't hold up to
this usage.
The units are:
Volts
Amps
Watts (volts x amps)
Watt hr's (watt's x hours)
A typical on-grid home might use 30kWh per day, an off grid one less
than 5kWh .....
Generators are used for battery charging or running loads too large for
the battery/inverter system to handle.
Ask away, and the experts here will answer your questions, and the
flakes will ridicule you and the experts.

Me too.

Sounds like you need to rediscover ohm's law (including the heatflow
version, with different units) and keep in mind the difference between
power (in watts) and energy (in watt-hours.)

Ok, I could probably look that up in my old awful physics book; I was
tempted to buy
Isaac Asimov's Understanding Physics book, thinking it might expain things
better and more clearly; does anyone recommend that, as compared to Ford's
Classical and Modern Physics?

Thanks for the help, guys.

updated the site?
