Transcript

  • 1. Renewable and Energy Efficient Technologies by EfficientCarbon
  • 2. A few basic guidelines • 2 hr session – 45 mins for theory – 15 mins of Q&A (at the end of theory) – 1 hr of demo/activity – Some climate change videos if time permits • Maximum Participation • Tell us if we are boring you to sleep  www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 3. Agenda • The current situation – Fossil Fuels - Greenhouse Gases – How Global Warming Works – Climate Change and India • The Carbon Economy Equation • Technologies for the future – Solar • The science behind the Solar Cell • What is the world upto • Advantages, Disadvantages and Applications – LED • The basics – science, fabrication and coloring • Advantages, Disadvantages and Applications • About EfficientCarbon www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 4. Fossil Fuels and Greenhouse Gases The global emissions have been steadily increasing since 1900 and the rate of their increase is going up as well. The six greenhouse gases to account for are, CO2, CH4, SF6, N2O, HFCs and PFCs. www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 5. How Global Warming Works Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas) www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 6. Effects of Fossil Fuel based Economy Globally Rising Sea Level Increased Temperature Damage to Biodiversity Changes in Water Supply www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 7. Effects of Fossil Fuel based Economy Globally www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
  • 8. Climate Change and India • Rise of Sea-level/Depleting water resources – Sea level is rising at 3.14 mm a year in the Sunderbans against a global average of 2 mm, threatening low-lying areas of India and Bangladesh. • Impacts on Agricultural yields – Indian agriculture supports around 60% of the population and contributes to around 17% of the GDP. For every 1* rise in temperature there would be a 6% reduction in the rice yields in India • Climate Refugees – Rising sea levels poses a threat of migration of people into other areas increasing the stress of infrastructure, basic amenities and job opportunities www.efficientcarbon.wordpress.com Phone: +91 9000345588 efficientcarbon@gmail.com © efficientcarbon, All rights reserved
