Affordable and clean energy is one of the 17 global goals which make up the 2030 Agenda for Sustainable Development. The impact of renewable source of energy is greater than non renewable towards achieving SDG.

 Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy often provides energy in four important areas: electricity generation, air and water heating/cooling, transportation, and rural (off-grid) energy services.

At the national level, at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply. National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond. Some places and at least two countries, Iceland and Norway, generate all their electricity using renewable energy already, and many other countries have the set a goal to reach 100% renewable energy in the future.

New renewable energy sources (excluding large hydropower) such as biogas, micro-hydro and solar energy contributed about 0.7% to the national balance in 2008/09 altogether. Although the share is still small, it has increased by 40 % since 2005.

Although there is a considerable lack of efficiency in energy use, Nepal accounts for relatively low CO2 emissions compared to other countries in the region. The reason is the high proportion of renewable energy sources (biomass and hydropower) in primary energy consumption. 

While we are talking about renewable source of energy, I will write about a hidden village of Nepal which I have recently encountered and it is following use of renewable source of energy.

Nepal is very right in high hills and mountains. During the course of time, I have recently visited Devchuli hills. These hills is almost 3 hours in motorbike far from the lowland city. The roads are very much vulnerable in condition. If a small electric vehicle called as Tuktukey in Nepali travel through the road from one side another side would get blocked. The road is by the high hills. 

It almost took 3 hours to reach the homestay where we decided to be for a night. This is a small introduction about how we reach there.

A real inspiring story begins here. When we were traveling towards our destination; the wind mill was seen. The weather pattern is very much fluctuating there but the wind is constantly flowing. Taking advantageous of this wind pattern, wind turbines have been set up and is used to generate electricity. Apart from this, solar panel is being set up in every house for electricity. They don't need electricity to draw water as they have 24 hours fresh water availability from waterfalls. The village has no television however they play radios and Cell Phone has also reached there very recently. They use biogas for the fire purpose. They use public vehicles that is rarely seen that is approximately 3 buses a day and few electric rickshaws. Meaning thereby, the need of electricity for them is very minimum which is greatly satisfied by wind turbines and solar energy. There are very few people in the village approximately 100_150 in total. These means of electricity through these renewable source of energy is sufficient enough for them.

This is a story of Devchuli people.

In addition to this, the major renewable source of energy in Nepal are:

1. Biomass. Biomass is by far the most important primary energy source in Nepal.

2. Biogas. 

3. Solar.

4. Hydro. 

6. Solar. 

7. Wind, etc.

In the end, renewable energy is of great importance. Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security, lower risk of fuel spills, and reduce the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.

It not only protects present generation but also preserves the property of future generation maintaining harmonious environment.
