    Correct. As is Biomass.

    I have bought more than 15 containers, and build with them and my clients as well. My first 40′ cost $1800 my last one cost me $3000. The price for a 40 and a 20 are about the same and the shipping is about the same (one truck, one container). Pricing and availability varies on the balance of trade moving in and out of CR. Lots of Chinese imports, and few exports = stockpiles of containers. Best way is to get other materials you need ready and ship them in the container to your site. If you need one I can give you my contact and she can get one. And no they don’t make much more than the processing fee to get it out of customs.

    Thats right David. And if we take a look at oil prices you can see why ARESEP will approve rate hikes. $92 a barrel today and going to over $105. The ICE cannot keep up with the economic growth in Costa Rica as the lag time to build new electrical generating capacity is not as fast as the growth in energy demand. This “demand gap” is filled by the quick deployment of fossil fuel burning generators, which are not only expensive because of the fuel component but the maintenance and capital costs are huge when generators are only used to supply peak outputs. Solar is cheaper than ICE $0.19 /kWh vs $0.33 kWh and also helps offset this peak demand when most needed. Why? Because when the sun is shining the brightest during the high season and tourist and seasonal owners have the air conditioning cranked up, the hydro plants are producing less power. Solar just makes good sense as it is producing the most amount of energy when it is needed, during hot sunny weather.

    If CR is to meet the CO2 Neutral targets it has set for itself then the continual addition of fossil fuel plants must be stopped. Offsetting a homes energy use with solar PV is an easy, quick and cost effective way to do just that.
