Written by a salesman. Six paragraphs to say we need better energy storage. Duh...

Exactly. Electricity is so cheap that people have lost sight of the real "costs" electricity generation. It's like water - as much as we want, available on tap. But we pay a heavy price for that, and it's not even necessary. Your Wintel PC sucks 100W instead of 10W because it can, not because it has to.

Micro power stations are quite interesting as mentioned above. Waste heat can also be quite easily used to perform tasks such as water and space heating that normally use electricity of some other energy. The biggest down sides of micro power is that it is much more expensive.. Micro power still needs to be grid connected so that this generation can be used in industry etc. Something along these lines is WhisperGen http://www.whispergen.com/. These are domestic (or small industrial) heater/generation units that make far better use of energy. They use stirling engines which are incredibly quiet.

One of the solutions to save on transmission losses would be to have micro power stations installed in each house or a colony or an apartment. Such power stations should run on the waste generated in that house/apartment/colony. The supplement could be given by the Solar panels or wind mills. Such micro power generation will have the double benefits -a) it will save huge capital expenditure incurred to build and maintain large power plants and b) It will make people aware of the cost of electricity generation and the value of the garbage they generate

Wrong. We need to dump the idea that electricity is always available 24-7 at a flat-rate price. Batteries cost more money than the actual PV panels - and exactly where do you think all the materials are going to come from to roll this out on a large scale? The more cost-effective solution is to implement demand billing, with only limited storage available. Customers who want/need uninterrupted electricity can pay accordingly - a lot when the sun isn't shining or the wind isn't blowing, and a little when it's readily available. The rest of us can scale back our usage (automatically, perhaps) as we see real-time prices rise beyond a level we consider worthwhile. Much better load-levelling, higher profits, and less complexity and cost.
