What Would It Take To Power New York State On Only Wind, Water And Sunlight?

Wind, water and sunlight power.

“We must be ambitious if we want to promote energy independence and curb global warming,”
Study co-author Robert Howarth, Cornell University

Professor Mark Z. Jacobson, a senior fellow with the Stanford Woods Institute for the Environment and the Precourt Institute for Energy, led a study to calculate what it would take to power the State of New York by 2030 with only renewable energy generated from wind, water and sunlight. Currently, almost all of New York’s power comes from gas, oil and coal.

Based on power demand forecasts for all industries, here’s what Professor Jacobson and his team determined would be needed:

  • 4,020 onshore 5-megawatt wind turbines
  • 12,770 offshore 5-megawatt wind turbines
  • 387 100-megawatt concentrated solar plants
  • 828 50-megawatt photovoltaic power plants
  • 5 million 5-kilowatt residential rooftop photovoltaic systems
  • 500,000 100-kilowatt commercial/government rooftop photovoltaic systems
  • 36 100-megawatt geothermal plants
  • 1,910 0.75-megawatt wave devices
  • 2,600 1-megawatt tidal turbines
  • 7 1,300-megawatt hydroelectric power plants, of which most exist

Looks like a lot and it is but it’s an investment. If installed, renewable energy would be the fuel source for vehicles, home heating and all industries in the state – it would be powering everything. Check out the full article on the study and find out how the plan, if implemented, would save billions in pollution related healthcare costs and help mitigate the future costs of climate change.

Solarclave Sterilizes Medical Equipment In Remote Areas Using Sunlight.

Solarclave from MIT's Little Devices groupIn hospitals, an autoclave is an electric-powered device that is used to sterilize medical equipment and supplies. The Solarclave, designed by MIT’s Little Devices group, is an autoclave that is solar-powered and can be used cheaply and repaired easily by remote clinics in developing countries. Here’s a description of the Solarclave from the Little Devices group:

“With a bucket, a pressure cooker, and 140 pocket-sized mirrors, IIH researchers have invented a device that uses sunshine to sterilize surgical tools. Solarclave provides reliable surgical sterilization for rural clinics outside of the grid – enabling healthcare workers to provide basic, life-saving services for patients.”

And here’s how it works (SmartPlanet):

“Under a clear sky, the system takes 45 to 60 minutes to heat up to a sterilizing temperature (250 degrees Fahrenheit) and then 20 minutes to carry out the sterilization cycle.”

The final design of the Solarclave was modified based on feedback from rural users in Nicaragua. [SmartPlanet]

Freewheelin Pedal Buses Will Be At The Democratic And Republican National Conventions.

Freewheelin 2012 Pedal-Powered BusesIt’s nice to hear that for the second time, the US’s two main political parties can agree on something. The Republican (Tampa, FL Aug 26-30) and Democratic (Charlotte, NC Sep 2-6) National Conventions will have the pedal-powered Freewheelin buses free to use between popular in-city destinations. Supplied by Humana, the 20 Freewheelin pedi-buses can accommodate up to 8 riders (+ driver) and are part of the health insurance company’s efforts to encourage healthy lifestyles and social interaction. The two plus days between conventions will be nice and will give Humana an opportunity to re-calibrate and adjust their pedal-powered buses that may “lean to the right” after the Republicans.
