Im 30 weeks pregnant, and I never want to clean, my house is starting to get trashed. I just have no energy. Any suggestions?

Same place you get the energy to brush your teeth.
You don’t look for it – you make it.
make a list of what has to be done and check them off one at a time.
You think you are tired now – just wait – I promise you have no idea what is to come!!

I am thinking of utilizing geothermal, wind, and solar energy generation. Can I do that on my land?

You need to find out what potential your property has. Any of the three will work but the question is what will be the better of the three and at what cost. Geothermal, while one of the best forms of electricity, is also the most expensive to place in areas where Geothermal heat is located to deep underground to be practical to be harnessed.

Wind energy can be very efficient and cheap to harness but in areas where the wind doesn’t blow consistently wind generation can be a frivolous pursuit.

Solar energy while not as efficient is very cheap and can be set up in pretty much any location that gets a good supply of light. The down side to solar energy is the fact that current capture capabilities of solar are only about 10% at the very best (8% is industry standard to date) The lack of efficiency in the collection cells makes it necessary to build Immense collectors to make up for the deficiency in energy capture.

You might begin by conducting a few simple tests to see what energy would best be created on your location. Other than that I would consider only making what you need to sustain your own life on 300 acres because what you will get out of a commercial endevour is minimal.

Solar cells convert the energy of incoming light to electric energy; a good quality cell operates at an efficiency of 15%. Each person in the United States uses energy (for lighting, heating, transportation, etc.) at an average rate of 11 kilowatts . Although sunlight varies with season and time of day, solar energy falls on the United States at an average intensity of 200 W/m^2.

Assuming you live in an average location, what total solar-cell area would you need to provide all of your energy needs with energy from the sun?

The correct rate is 11kWhr per day. 11kw would be a horrendous amount of power.(maybe Al Gore uses it at this rate)

I will calc it at your rate for problem sake. (this is not real life by the way, there are lots more variables, length of day, etc)

200W/m^2 * 15% = 30w/meter

11kw / 30w/meter = 366m^2

On a side note I think mastering physics is a crappy program, made for lazy physics teacher that dont ever care about application of knowledge.

advantage: we dont waste the earth, there is tons of it (thus the word renewable so we will never run out.
disadvantage:it costs ALOT more than other energy sources, because of trasporting it

I’m not saying I’m against renewable energy. I’m just wondering – what would everybody do with their car that runs on regular gas?

I think we are a long way from renewable energy replacing the combustion engine. When I think of renewable energy I think of electricity for houses and businesses. But when we do settle on one or a few technologies to replace the conventional gas engine. I think there will be a transitional period where new cars will have the new technology but we will still have the infrastructure for gas engines, it could take decades to phase out the older cars.

Here in CA we have tougher emissions laws, so if you have an older car you could get an exemption for not passing emissions, it was a program that let just the oldest cars be exempt, then every few years they let a few more years be exempt. Now all the cars that were sold after the date the laws went into effect have to pass smog, if you didn’t buy the car in CA then you will need to get a catalytic converter put on it to pass. Millions of cars are junked each year, when you turn in an old clunker when you buy a new car they are often sold for scrap and they are taken off the road. All that being said, to say that people won’t be forced to convert cars or get rid of them for many many years.
