World’s tallest hybrid wind turbine installed in Kutch

Wind turbine manufacturer Suzlon Energy has installed the world’s first and tallest hybrid wind generator turbine in Kutch, Gujarat. This installation was part Gujarat’s focused approach on enhancing Renewable Energy Portfolio in order to meet the dual objective of Sustainable Development and ensuring India’s Energy Security.

In 2008, the Suzlon Energy had signed a memorandum of understanding (MoU) with the Gujarat Government to set up 2000 MW of wind energy capacity in the state.

Key features of Suzlon’s tallest hybrid wind generator turbine

  • The turbine will generate 12-15 percent more energy.
  • Hybrid wind turbine will be 120-metre in height. It is taller than conventional wind turbine towers by 40 metres.
  • With this new turbine, the installed wind energy capacity at the Kutch region of Gujarat has gone up to 1100 MW. It makes it the Asia’s biggest wind energy park at one location.
  • This tower is ideal for low wind areas and the potential is huge. In the next three years, this region will have 2000 MW of wind energy capacity.

About Suzlon Energy

Suzlon Energy is a leading wind power products and services company with a global footprint. It was established in 1995. Suzlon is credited with developing one of the world’s largest wind farms in the western Indian state of Gujarat and Rajasthan.

The company has presence across six continents: North and South America, Asia, Australia, Europe, and Africa. The Suzlon Group has built its presence in over 31 countries and has achieved a milestone by crossing over 25000 MW of wind power installations globally.

Canine Distemper Virus pushing tigers towards extinction

According to a new study from the Wildlife Conservation Society (WCS), canine distemper virus (CDV) has the potential to be a significant driver in pushing the tigers towards extinction. This deadly virus is adding a new threat to tiger populations along with to the existing pressures of habitat loss, poaching and depletion of prey species.

Researchers have evaluated these impacts on the Amur tiger population in Russia’s Sikhote-Alin Biosphere Zapovednik (SABZ), where tiger numbers declined from 38 individuals to 9 in the years 2007 to 2012.

How the study took place?

  • The scientists used computer modeling to simulate the effects of CDV infection on isolated tiger populations of various sizes and through a series of transmission scenarios.
  • These included tiger-to-tiger transmission and transmission through predation on CDV-infected domestic dogs or infected wild carnivores (such as foxes, raccoon dogs and badgers).
  • High and low-risk scenarios for the model were created based on variation in the prevalence of CDV and the tigers’ contact with sources of exposure.

A key finding of this study

  • Modeling shows that smaller populations of tigers were found to be more vulnerable to extinction by CDV.
  • Populations consisting of 25 individuals were 1.65 times more likely to decline in the next 50 years when CDV was present.
  • The results are profoundly disturbing for global wild tigers as in most sites wild tigers are limited to populations of less than 25 adult breeding individuals.

About canine distemper virus (CDV)

Canine distemper is a viral disease that affects animals. The disease is highly contagious (via inhalation) and fatal 50% of the time, thus making it the leading cause of infectious disease death. The virus infects the gastrointestinal tract, respiratory tract, the brain, and spinal cord of animals.

Common symptoms can include: 1) High fever, 2) Watery discharge from the eyes and nose, 3) Vomiting and diarrhea, 4) Hardening of the footpads and nose, 5) Seizures of any part of the body 6) Paralysis.

It is most commonly associated with domestic animals such as dogs and ferrets, but it can infect wild animals.
