Green Technology Used to Combat Climate Change – Infographic

Scientists have been sounding the alarms about climate change for decades, but unfortunately we are still completely dependent on digging stuff up and burning it for our main sources of energy. The United States gets 39% of its energy from coal, which is ok from a national security standpoint until the acid rain makes our water undrinkable. Natural Gas pollutes 30% less than coal and the U.S. gets 27% of its energy from that source, but there are still significant pollution issues. And, of course, there is a threat of a meltdown, but mainly the radioactive waste is dangerous for 240,000 years.

People have been looking for alternative energy sources for decades, but progress in getting them installed means less than 15% of the energy produced in the United States comes from renewable or clean sources. Hydropower is the largest sector of green energy in the U.S., responsible for almost 7% of the power production. It is, however, not without its own issues- dams can endanger ecosystems, so hydroelectric power has to be done properly. Wind is an emerging energy sector at almost 4.5% of America’s power grid. Just one percent of power produced in the U.S. comes from solar or geothermal sources, though that number is always increasing with improvements in technology.

Transportation is one sector where small improvements in efficiency can have a huge impact. Increases in mandatory fuel efficiency have decreased air pollution since the 1970s. Continuing to increase efficiency will continue to improve the environment. Biofuels have also shown promise in decreasing pollution. Now many people are even driving hybrid electric and full electric cars. When powered with solar power they produce zero emissions, and even when they get their power from traditional sources they still pollute less than traditional internal combustion engines.

Year Long Study of Net-Zero Energy Home Completed Successfully

home

It has now been a year since the Net-Zero Energy Residential Test Facility (NZERTF) in Washington DC has been built and its energy harvesting capabilities began to be monitored. The home was built on the campus at the National Institute of Standards and Technology (NIST), where scientists and researchers conducted a computer simulation that replicated the energy consumption of a family of four. The results showed the home to be a success, since after a year the home generated 13,577 kWh of energy. This is about 491 kWh more than was needed.

Light Filled Net Zero Home

ext

The San Francisco based studio, Klopf architecture, in collaboration with mechanical engineering firm Monterey Energy Group has successfully completed a net-zero energy house in Cupertino, California. The renovation of the existing home on the site was aimed towards scoring as high as possible on the “GreenPoint Rated System.” The result is a two-story home that is filled with natural light and is capable of producing as much energy as it requires. The net-zero status of the home was achieved through features such as insulated concrete forms, structural insulated panels, high-performance windows, cementations siding and a rooftop-mounted solar photovoltaic array.

Harold Turner’s home near Concord, New Hampshire measures 3,370 square feet and was built using the ROSE construction method, which was created to build affordable net zero energy and cost effective homes in a wide variety of geographical locations and environments. R stands for “Renewable energy production,” O and S stand for “Owner driven spatial design,” and E is for “Energy efficient construction,” while the entire house is known as ROSE cottage and serves as a prototype and test bed for future homes to be built using this method. The entire home was built for $175 per square foot.

Net-Zero Living in Equinox House

Equinox House - 11-13-2013-700x334

When their children went off to college, Professor Ty Newell and his wife Deb were faced with the so-called empty nesters problem of finding themselves living alone in a house too big for them. Instead of just buying a smaller home, the couple decided to build Equinox House, a net-zero home located in Illinois. The house was designed and constructed by Ty and his son Ben in 2010.

A Zero Net Energy Prototype House Built in California

deyoung-zeronethome

Last week, the Zero Net Energy (ZNE) house was unveiled in Clovis, California. The three-bedroom, two-bathroom home has a living area of 2,064 square-feet and was built as a join effort between BIRAenergy Consulting and De Young Properties. Pacific Gas and Electric (PG&E) offered technical assistance to the builders in trying to find ways of getting the home to use only one-third of the energy needed for a house built to minimum code. ZNE House was built to become a model for future net zero homes in the area.

The house features numerous energy-efficiency improvements, which are in accordance with California’s Long-Term Energy Efficiency Strategic Plan. This plan stipulates that all new residential construction in California will be net-zero by the year 2020. The house will not be made available for purchase yet, as it will serve as a prototype to study how well it functions and what improvements have yet to be made.
