Amidst the time when the experts have started to throw in their contemplations regarding whether the Paris summit in December 2015 will “save the earth”, or will just end up as another Copenhagen, India has come up with a unique business opportunity that sees a target of setting up 100,000 MW of solar energy by 2020.

A senior government official stated that the rooftop solar projects offer a big business opportunity upto the tune of Rs. 4 lakh crore.

“Grid connected rooftop solar power is the most important sector as far as renewables are concerned. This 40,000 MW project requires an investment of up to Rs. 4 lakh crore and is a big business opportunity for all,” said Tarun Kapoor, joint secretary, ministry of new and renewable energy (MNRE), addressing a conference in the capital organized by The Energy and Resources Institute (TERI).

In regard to the system by which people who set up solar power panels on their rooftops can sell electricity back to the grid, he said that there are 20 state regulators who have issued connections whereas 17 states have issued policies for net metering.

Also an objective of achieving 100,000 MW from solar energy by 2020, 40,000 MW of which will come from rooftop solar power, has also been set by the government.

“Taking a systemic approach towards implementing this large and ambitious programme, ensuring it is a win-win for all stakeholders is critically important,” added Leena Srivastava, acting director-general of TERI.

  • NASA’s new instrument can measure Sun’s incoming energy
  • The instrument is called Total and Spectral Solar Irradiance Sensor (TSIS-1)
  • This can help bring in an energy revolution in future

To continue long-term measurements of the Sun’s incoming energy, NASA has powered on a new instrument installed on the International Space Station (ISS).

Sun
Solar energy is one of the biggest energy sources in the world.

The instrument, Total and Spectral solar Irradiance Sensor (TSIS-1), became fully operational with all instruments collecting science data as of this March, NASA said.

“TSIS-1 extends a long data record that helps us understand the Sun’s influence on Earth’s radiation budget, ozone layer, atmospheric circulation, and ecosystems, and the effects that solar variability has on the Earth system and climate change,” said Dong Wu, TSIS-1 project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. TSIS-1 studies the total amount of light energy emitted by the Sun using the Total Irradiance Monitor, one of two sensors onboard.

This sensor’s data will give scientists a better understanding of Earth’s primary energy supply and provide information to help improve models simulating the planet’s climate.

The second onboard sensor, called the Spectral Irradiance Monitor, measures how the Sun’s energy is distributed over the ultraviolet, visible and infrared regions of light. Measuring the distribution of the Sun’s energy is important because each wavelength of light interacts with the Earth’s atmosphere differently.

For instance, spectral irradiance measurements of the Sun’s ultraviolet radiation are critical to understanding the ozone layer — Earth’s natural sunscreen that protects life from harmful radiation.

“All systems are operating within their expected ranges,” said Peter Pilewskie, TSIS-1 lead scientist at the University of Colorado Laboratory for Atmospheric and Space Physics in the US. IANS
