LED lights / bulbs are a small but great investment in terms of % saved. They have great ROI, cut down on power bill costs and might also reduce the CAPEX of a solar investment (because you'll need less power).

Most home solar systems are limited to 10K. Beyond this point the utility company starts adding fees and regulations. Building an energy efficient home is a critical part of the broader picture. Even a 10KW system will not produce enough power for the average 4 bedroom home in the US unless the house is very efficient.
A completely self sufficient home in my opinion is the ideal. The ecocapsule is a good start similar to how the Tesla was a good start toward the electronic car.
The ecocapsule is a good investment because it's mobile, it's moderately self sufficient, it's only drawback is it's not cheap. Because of trends in crypto I expect solar generation and other forms of distributed generation will be tokenized and we are beginning to see it with Solarcoin. Distributed generation and self sufficient homes are really one of the only long term paths to economic independence.
The ecocapsule can generate it's own electricity. It can capture and clean it's own water from rain. And can generate from wind. It still needs to be perfected though.

I dont even get it how the Tesla guy, managed to sell and promote a single grid tie solar system... in the year 2016, and present it as new technolgy.... besided the fact that it looks good... is so simple and so undertech than other companies producing solar products for the last 20 year... But thas another story, of good marketing and using your fame to make more money...
I would love to put ecocaptule on wheels and ride the world by the way :)
When a system is named 10kw, its real time usage will be maximum 8kw, and this power will be achieved probably from 11:00 to 16:00
After that... or before that... it falls even lower, until it reaches 0, and the inverter turns off...
Heat, angle of the solar powers facing the sun... (prefered orientation for europe is NORTH) north will produce 100% efficiency in perfect conditions, and EAST 90%, but even that 10% will be much difference in the end of the year.. Perfect conditions sadly never exist....
Even more, your solar inverter must be efficient.... same story like Psu's in computers, gold platinum, bronze power supply...
And always use a bigger inverter than your grid system, in order to avoid using it 100% all the time, cause it breaks its efficiency even lower...
for example my named production is 8.5kw, but my inverter is for 12kw.
So when is the market going to adapt and stop buying homes which are inefficient and unsustainable? I see no reason to buy a home which costs in property taxes, and in maintenance, and in utility bills, and it's not mobile?
Why not just buy stock? You might not get 13% a year but you can get 6%, but it's also more liquid and about the same risk. As far as the housing market goes, it's for sure in a bubble. Most houses aren't worth anywhere near what people are currently paying and with 3d printed houses coming it's going to be very clear soon.
Sustainability is key.
