Germany sets new solar power record

Germany is the world leader in Solar Power.

Came across this interesting article from Reuters about Germany’s Solar Power Record: “Germany sets new solar power record, institute says”

This Friday and Saturday, when sunlight was quite good, Germany generated 22 GW (1 GW or Giga Watt = 1,000 Mega Watt) of solar power for a few hours in the afternoon! That is nearly 50% of its power requirements (note requirements on weekends are less, since factories and offices are closed). Still this is quite a milestone!  For comparison, the biggest power consuming state in India, Maharashtra consumes about 15 GW of power.

Came across quite a few interesting data points from the article:

– Germany generates about 4% of its total electricity needs annually via solar power.

– Total renewable energy generation is 20% of its total needs.

– Total installed capacity of Solar Power in Germany is nearly half of the installed capacity in the whole world.

– Germany added 7.5 GW of installed power generation capacity in 2012 and 1.8 GW more in the first quarter for a total of 26 GW capacity.

– Germany has a total installed solar power capacity of 24 GW

– From the article: “Utilities and consumer groups have complained the FIT for solar power adds about 2 cents per kilowatt/hour on top of electricity prices in Germany that are already among the highest in the world with consumers paying about 23 cents per kw/h.”

– But the solar power costs might come down as photo-voltaics become cheaper each year.

Some quick implications for India

India has lot more hours and months of sun as compared to Germany. Cost of photo-voltaics is coming down, making solar power more competitive. Solar power seems a lot more attractive renewable energy option, as compared to wind. Gujarat has taken the lead in installing solar power. Maharashtra, Karnataka and other states are also setting up solar fields, but the progress is slow.

India needs more policy focus and better execution to make solar power a successful reality.

Currently, China is the world’s major exporter of photo-voltaic cells. India needs to expand production of photo-voltaics. Similarly, other new related areas such as concentrated photo-voltaics (CPV) should also explored.

It is worth noting that Solar Power (or for that matter, any renewable energy source) is not a panacea for energy requirements… at least definitely not in the coming decade. Even in Germany today, Solar Power contributes single digit percentages annually of the total energy requirements. Thus, India will still need to expand its electricity production from conventional and nuclear power sources. Still, in an energy starved India, 10% renewable solar power in a decade, with no dependence on foreign fuel, would be a great step.

Incentives for Preserving and ‘Recreating’ Heritage Architecture In New Buildings

Posted in Current Affairs, History, Pune by Amit Paranjape on May 16, 2012

It is really sad to see the crazy expansion of concrete, steel and glass in Pune, with completely haphazard architecture standards. It is the same state in all major cities in India. In many cases, there is an attempt to emulate foreign architecture concepts that don’t blend in here very well. This extends to those ridiculous sounding names in English (and French, Italian, Spanish)!

I think it is the responsibility of local civic authorities (as is done in many cities, in the developed world), to enforce some kind of consistency standards in architecture of buildings, landscapes and ideally, even the names!

Just as there are green building requirements and certification standards, civic authorities need to enforce such standards for basic architecture. There have been many discussions on this topic, but doubt if any Indian city has done any progress in this area. I am going to take this requirement one step further. Not only should basic architecture standards be enforced, but heritage architecture should be provided with incentives (I am not asking for enforcement here… but some positive reinforcement).

For example, if a building (or more specifically, a private bungalow) tries to use the old Pune ‘Wada’ type architecture, or the early 20th century ‘Stone’ construction, they should be offered some benefits. We have to encourage new development that respects, preserves and recreates our heritage.

Similar small token incentives should be given to using local and Indian names. Instead of the often horrible (supposedly ‘aspirational’) sounding western names that we see everywhere today, we should encourage the use of local/regional names. Pune was the city of gardens (‘Baugs’) during the Peshwe Era. We had great gardens such as Hirabaug, Sarasbaug, Tulshibaug, and many others. Today, it would be great to see some apartment complexes named as ‘XYZ-Baug’.

In addition to local authorities (like PMC) providing incentives; NGOs and other organizations who are working in the area of heritage preservation (e.g. Janwani in Pune) should also institute prizes and awards for buildings that go out of their way to preserve and replicate the heritage.

Would like to hear the readers thoughts on this topic. Has something like this been done effectively in any Indian city? Note, I agree that ‘incentives’ are a small step, amongst many others to preserve our rich (but poorly maintained and fast dwindling) heritage.
