Passivhaus/Passive house design that saves mucho energy, does not require air conditioning, does
not require heating even when outdoors it's 10 below! Since, for example, more than 30% of energy consumed in the UK is for homes and 82 per cent of that is space and water heating, [Monbiot, "Heat,"chapter 5, "Our Leaky Homes,"] changing our standards of home design is important.
Diagram
shows that basic solar design concepts are well understood and technically easy to implement in new construction. [If only my house could be turned 45 degrees!] Possibly through ignorance, and partly through the desire to cut corners instead of doing things right, we do not make these wise concepts a priority. There are lots of
cool alternative building techniques, many of which are
traditional and being revived. This
leading design standard saves 90% of energy used in the home. Here in Canada it's called the
net zero energy home.

Will algae defeat global warming? "Fed a generous helping of CO2-laden emissions, courtesy of the power plant's exhaust stack, the algae grow quickly... The cleansed exhaust bubbles skyward, but with 40 percent less CO2... The algae is harvested daily and a combustible vegetable oil is squeezed out: biodiesel".

Pederasts of the
mind: Of
kids, lies and Oil. The American Petroleum Institute
partners (in 2004)
with The
National Science Teacher's
Association (NSTA) and
Scholastic
(see: Scholastic's
creedo) to
provide K-12 lesson plans, on energy and oil, which resemble the
API's own "Teacher Lesson
Plans" and snappy
flash presentations such as
Progress
Through Petroleum! which are bundled with
fun stuff and
cool facts. The NSTA/API lessons teach all about energy and oil except the
global environmental impacts. Didactic bonus from
NSTA's oil-friendly curriculum :
a surrealistic gallery of oil industry
imagery for kids to download.
