Could Indian Railways be Solar self sufficient?

Indian Railways is one of the largest consumer of both diesel oil and electricity in India. It uses 2.7 billion litres of diesel and around 20 billion KWh of electricity per year for traction purpose. Additionally another 2.5 billion KWh is used for non-traction related usages like powering stations and other things. This 2.7 billionContinue reading “Could Indian Railways be Solar self sufficient?”

Solar: Is it an option for aircrafts and shipping

Solar energy is considered as the ultimate source of energy. In the last few years due to technology and abundant production of silicon, solar technology has become very commercially viable and it is rapidly approaching grid parity. Effect of this could be seen in transportation also. Numerous solar vehicles have been tried or announced. SomeContinue reading “Solar: Is it an option for aircrafts and shipping”

Nuclear vs. Renewables. A Carbon free competition

Before we start, let us do a small exercise. Just go back one decade, to around 2002. That was the time when people started noticing more about Global Warming and Climate Change. If someone considers about getting rid of fossil fuels at that time he or she had a very limited options which were costContinue reading “Nuclear vs. Renewables. A Carbon free competition”

Can we avoid Energy Storage

There have been a lot of focus about energy storage these days coupled along with solar and wind. As a coin has two sides, Energy Storage has both pros and cons. Some of the main concerns I could gather are: Prohibitively Expensive Capital Cost: Energy Storage systems are expensive to own. Cheapest solutions like LeadContinue reading “Can we avoid Energy Storage”

Problems of Lunar Solar Power

There have been a lot of proposals about having Solar Power Stations on Moon. The plan is to create a belt of solar modules around 11000km equator. The power will be taken to Earth using Microwave beams. After going through some of their ideas, I thought it was not an idea at all. Some ofContinue reading “Problems of Lunar Solar Power”
