Bush has let the MARKET, or lets get personal, you decide. It is not the presidents job to make choices for YOU, get it???? YOU must decide what is renewable. Some believe oil is, yes, it is, long long term. So it's YOUR PERSONAL choice, have biodiesel or food to eat or use petroleum. There is no middle ground, it's a choice, are you smart enough to decide or do you need to run to your mommy (government) to tell you (when to blow your nose)?

and we can not make more to keep up with the worlds consumption so try again

I think Bush has done more against renewable energy than any president before

seems i'll have to get back to you on that.

you could say corn ethanol, but that's raised the cost of food, and with an expanding population, that's surely not going to be practical in the future.

Before trying buy a solar electric system to offset your electrical load there are at least 2 things you should consider first: 1) how can you make your home more energy efficient and reduce your power consumption in the first place 2) if you use electricity to heat your water or the air in your home then buy a solar water heater and solar air heaters, respectively. The latter is far more cost effective than buying a larger solar electric system to heat either the water or the air, and they will generally pay for their initial upfront cost in 3-8 years (solar electric systems currently (2008) take 15-20 years to pay themselves off without a rebate program).

Solar water systems for an entire home cost from $1500-$4500. If you are an advanced Do-It-Yourself you can save thousands by installing yourself. I'd still recommend getting a licensed plumber friend over to make sure all of your soldered unions were done well.

Solar Air heating systems range in price from $1100-$2000 for collectors that heat rooms from 300-750 square feet. These collectors offset about 30% of your heating needs for that space and are fairly easy for the weekend Do-It-Yourselfer to install.

Once you've done all you can do make your home more efficient and to use solar heating (solar thermal) technologies to reduce your electrical loads, then it's appropriate to consider a solar electric system.

If you are looking to start small and power say a room or two in your home, then you're probably looking at an investment of $2000-$4000. Solar electric systems which allow you to live independent of the electric utility grid (known as "off-grid") generally cost about 30% more than systems that are connected to the electric network (known as "on-grid" or "grid-tie"). A whole home system can have a raw upfront cost of $20000 and up (without any rebate or tax credits).

The maintenance costs are minimally for both off-grid and on-grid solar electric systems. The difference is that off-grid system have batteries which require someone to do monthly maintenance on (i.e. checking their electrolyte levels and occasionally adding distilled water). Since solar electric systems have no moving parts they can easily last decades with minimal maintenance or repair.

The good news is that if you are in the USA, as of 2009 the federal government offers an unlimited tax credit for solar electric systems ($2000/year tax credit for solar water heating systems). Additionally, many states also offer rebates for solar electric (and heating) systems. These rebates can offset as much as 1/2 of your costs for both the system and the installation itself (if done by a professional). Some programs won't provide you with a rebate if you do it yourself.
