Re: Energy efficiency and alternative energy sources
In Isaac Asimov's famous Foundation Trilogy, the mastermind of the backstory, predicting the collapse of a galactic empire, established a "Foundation" of intellectuals on a planet with very few usable natural resources.
This led directly to the development (over a long period of time) of highly efficient technology, as per the plan.
I think (hope) we are now at the point where we can skip the collapse of a galactic empire and go straight to the development of highly efficient technologies. Very good batteries are in development, solar cells are increasing in efficiency, wind farms are cropping up even here in the wilds of Northern Michigan, tidal hydroelectric plants sound good, highly wasteful light bulbs are being replaced by highly efficient LEDs (my aquarium light bulb is a LED array. It is very bright, uses only tiny amounts of electricity, and generates no detectable heat. I find it almost as fascinating as the plants and critters it illuminates).
I even hear tales of the development of artificial chlorophyll!
I'm not an engineer so I don't know much and can't make predictions, but I think we are headed down the right road at last.Every moment of a life is a horrible tragedy, a slapstick comedy, dark nihilism, golden illumination, or nothing at all; depending on how we write the story we tell ourselves.

Re: Energy efficiency and alternative energy sources
I'm very excited about the cost decline for LED lighting. We've begun to replace the few non-CFLs we've had lurking around with LEDs. We usually leave our light bulbs behind when we change apartments, but I think we'll take these with us!A human being is part of the whole, called by us 'Universe,' limited in time and space. He experiences himself...as something separated from the rest--a kind of optical delusion of his consciousness. This delusion is a prison for us... Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the of whole nature in its beauty...

On the subject of alternative energy, I really like the idea of solar power. What I had is that it's still not terribly efficient. Places that have solar panels, which are extremely expensive, often use regular power or wind, if they're lucky enough to be able to afford that too/live in a place that they can do it.

The efficiency of solar power has increased from somewhere around 1-7% collection to 44% in the past 40 years (this depends on type of panel), and the the size and cost of a panel has decreased just as dramatically to produce the same amount of electricity (and continues to do so). The theoretical maximum of current best technologies is somewhere around 65%. The problem of solar has never been about efficiency--there's more than enough sunlight available, provided one has enough surface area. Solar cells have also come down in price significantly, plus tax incentives and grants, etc can often cut the cost quite a bit. Considering the savings in bought electricity, the system in the long run can pay itself off in about 10 years (give or take a few depending on where you are, what you use, and what you bought, what incentives you got, etc)...and even if you don't plan to stay put, in increases your home value for resale quite a bit (more info).Wonderful Life: The Burgess Shale and the Nature of HistoryPagan Devotionals, because the wind and the rain is our Bible

Re: Energy efficiency and alternative energy sources
We have tried to use energy efficient techniques with building our house, within the limits of our budget. Passive solar design can make a big difference to heating and cooling costs, which reduces energy usage. We are double glazing the whole house and have ramped up the insulation. Even seemingly innocuous things like the colour of our roof and the type of roof ventilation were chosen with energy efficiency in mind.
Solar power is on our list of upgrades, but wasn't quite manageable up front. My parents' solar panels actually earn them money for most of the year... and when their new house is built down the farm they will actually be off grid and solar-only (the current shed weekender is run 100% on solar already, but there's no actual house there yet). They are also building with straw bale walls and double glazing, for improved energy efficiency.
I would love to be able to do geothermal heating rather than a traditional system. One day perhaps.
