Solar is great. But, what happens when monsoon sets in? This is not a problem for most of Tamil Nadu but what about places where it does. And then there are other places where wind offers great potential but not so in summer. Is there a way to offset these seasonal changes? Yes, the answer is – Wind Solar Hybrid System.
With Wind Solar hybrid system, you can benefit from both forms of energy sources which happens to give way to each other in different seasons of the year. But, for the hybrid system to work, atleast 60% of the power must come from ‘wind’ and the wind speed should be atleast 15 kmph on a average. The hybrid system generates as much as 5 units of power every day. And you know what is even special? – The cost of Hybrid system is 40%-50% cheaper than pure play solar system. All it requires is a 8 sq.m for 1 KW installation on your rooftop.
Small Hydro / Micro hydel projects / Watermills
While efforts are being made to make renewable energy available for everyone in Tamil Nadu, there are parts of the state that would be slow for adoption for practical reasons. Thanks to Micro Hydel projects which bridges this inconvenience. As the name suggests, Micro hydel is basically really small hydel installations enough to generate power for, let’s say, a tea garden. Many tea garden owners have found much help from it and have adopted already.
Local organizations such as the Water Mill Associations, cooperative societies, registered NGOs, local bodies are being encouraged to install watermills in their areas. A number of NGOs are now propagating water mills for electricity generation to meet small scale electrical requirements of villages. The water mills costs approx. 2 lakhs/KW.
Subsidy for Watermills and Micro Hydel Projects:
1. Mechanical output only – Rs. 35,000/- per Watermill
2. Electrical output (up to 5 kW) – Rs. 1,10,000/- per Watermill
3. Both mechanical & electrical output (up to 5 kW) – Rs. 1,10,000/- per Watermill
4. Micro Hydel Projects up to 100 kW Capacity – Rs.40,000/- per KW
Battery Operated Vehicles
If you are a youngster and wonder how you can contribute to a better world, perhaps this one is for you. Adopt to battery operated vehicles(BOV). They are clean, less burdensome to our planet, doesn’t pollute our air, almost never contributes to the noise pollution and most importantly for you, doesn’t cost you thousands on fuel. Many advancement in technology is making battery operated vehicles perform as much as the traditional ones. With time, its only going to get better.
BOVs can be operated as public transport vehicles — BOVs are available as passenger cars, 10 seater auto rickshaws and 12 seater vans. MNRE even provides subsidy for the same.
Here are some reasons you should consider BOV:
1. They have zero emissions and do not pollute the atmosphere.
2. They cost about Rs.25,000/- to Rs.40,000/- (subsidy of Rs.4000/- & Rs.5000/- for low & high speed vehicle respectively) and consume only about 1.5 KWhr of electricity to travel 60 km.
3. They can go about 30–50 km on a single charge. This capability meets the needs of an average, two wheeler-riders.
4. Most are used during the day and can be charged late at night, which is advantageous in balancing the electric power load.
5. Electric bikes reduce human exertion. They are structurally simple, convenient to charge, and easy to operate. Users do not need a driver’s license to operate them.
6. They are compatible with city roads.
7. They will reduce traffic congestion in the cities.
8. They will help reduce energy consumption. Their annual operating cost is about 15% of that of motorcycles.
