Transcript of Energy Efficiency
Energy Direct Harnessing Electricity Generation Transportation Light Bulbs Shift from incandescent light bulbs to CFLs/LEDs
Motion sensors/automatic dimmers Electric Power Wind turbines The Three Principle Components Wind Geothermal Hydroelectric Wind turbines in the United States In 2009, renewable energy accounted for more than 55% of all new electrical capacity installations.
Between the years of 2000 and 2009 renewable energy generation increased an average of 14% per year.
In 2009 alone wind capacity installations increased by 39%.
In 2009 wind energy accounted for 92% of installed renewable electricity capability. Future goals Currently Denmark has over 20% of their energy supplies by wind. Their government plans to increase this to 50% by 2025.
In Turkey, the government has allowed permits for 7,000 MW of wind energy proposals.
In 2010, the Scottish government announced its new goal for renewable energy to make up 80% of their total energy consumption by 2025. Wind energy is growing annually at an exponential rate But here are some current statistics… 1. Portugal
Total capacity – 3,960 MW
Total capacity – 4,611 MW
3. United Kingdom
Total capacity – 5,707 MW
Total capacity – 6,060 MW
Total capacity – 6,200 MW
Total capacity – 14,550 MW
Total capacity – 21,150 MW
Total capacity – 27,981 MW
9. United States
Total capacity – 42,432 MW
Total capacity – 52,800 MW (as of 2011) Harnessing Solar Energy The amount of solar energy that falls on the earth’s surface in 40 minutes equals the total annual energy consumption of all the world’s people.
Put differently, 27 years’ worth of worldwide energy consumption equals only one day’s worth of solar energy hitting the earth. Stabilizing Climate Change Future Goals Morocco has planned to build five large solar generating project each of which ranges between 100 to 500 megawatts in size.
Italy projected that it would reach 15,000 megawatts from solar power by 2020.
And Japan is planning 28,000 megawatts of solar power by 2020.
Even California has planned to reach 3,000 megawatts by 2017. Solar Panel Energy 1. Australia
Total capacity -- 700 MW
Total capacity – 1,500 MW
3. Czech Republic
Total capacity – 2,000 MW
Total capacity – 2,500 MW
Total capacity – 2,900 MW
Total capacity – 4,200 MW
7. United States
Total capacity – 4,200 WM
Total capacity – 4,700 MW
Total capacity – 12,500 MW
Total capacity -- 24,700 MW Solar collectors and Solar Heaters CSP- Concentrating Solar Power
Today there are three common versions of this: Household Appliances Power tower system Building Structure Efficiency Transportation Parabolic Trough System Encouraging Recycling Parabolic Dish Systems CSP’s potential Trains CSP compared to most renewable energy sources is very new and there is a huge opportunity for advancement.
Although the first plant to be created was in 1991, it wasn’t until 2007 that another plant was built.
According to the American Solar Energy Society, solar thermal resources in the U.S Southwest has the ability to satisfy current U.S electricity needs four times over. (as of 2011) Two Methods Progress Present Day 10,700 megawatts online
100,000 megawatts used directly
Iceland Future 3,000 megawatts currently under construction
Pertamina Limitations Solar Panels Heating and cooling Hydropower Currently provides 16% of world's

Reduce use of energy by 40%
Result: $4.4 million saved/year Clinton Foundation's Energy Efficiency Building Retrofit Program Carbon Reductions Germany pushing for efficiency
Edward Mazria and the 2030 Challenge in New Mexico
U.S. Green Building Council (USGBC)
Leadership in Energy and Environmental Design (LEED) Chesapeake Bay Foundation building, Chicago law firm, Bank of America Compact Fluorescent Lamps (CFLs) LEDs 75% 85% "All told, shifting to CFLs in homes...would cut the world share of electricity used for lighting from 19 to 7 percent."
--Lester Brown "The first step in increasing efficiency and cutting carbon emissions is to simultaneously restructure and electrify the transport system to facilitate the shift from fossil fuels to renewable energy." Bikes & Buses Bogota, Colombia Paris, France Reduce the use of fossil fuels Decrease U.S. fleet --> already begun
"Young people" losing interest in cars
Increase standards on fuel efficiency
Alternative modes of transportation Japan, France, Germany, Spain.......China, United States "Pollution is a symbol of design failure."
--William McDonough Some garbage stats...
54% to landfills Steel, bottled water, etc.
we need to encourage recycling SOLAR Fin http://www.worldometers.info/ Fin Fin
