When and where people use them? People use them to enlighten a place when there is load-shedding.

To ignite them we need energy. There are two sources of energy.

The energy source that will come to an end is called nonrenewable energy. For example: Gas, coal, petroleum, nuclear energy. The energy source that will never come to an end is called renewable energy. For example: Solar, wave, biomass, water, wind, geothermal energy.

Renewable Energy Resources-1 Unit-11, Lesson-1

Learning outcomes By the end of the lesson students will be able to… 1. ask and answer questions about renewable energy. 2. read intensively and extensively. 3. learn some vocabularies. 4. complete chart using appropriate information.

Sohan lives in a village in the south-west part of Bangladesh. Last night he could not sleep. His sister had her SSC exam next morning. She could not read either. There was load-shedding. The summer night being muggy and hot, life became hell without electricity. Most of their area remained dark for hours due to power shortage.

In May-June, temperature shoots up to 40 degree Celsius. With almost 90 per cent of humidity in the atmosphere, it becomes all wet, damp and sticky. When you are busy fanning yourself all the time, how come you concentrate on studies?

In the night it is impossible to sit in the study with a candle light or table lamp or hurricane lamp or a rural kerosene lamp. People simply come out of houses almost bare-bodied and sit in the open places. Some splash cold water on their faces. Fans remain unmoving, electric bulbs are off and it is dark everywhere. It is simply unbearable.

What is the reason of frequent load-shedding? Press reports say there is a shortage in electricity production. According to the Power development authorities, the demand for electricity a few years ago was more than 6, 000 MW* a day while the supply remained around 4, 200 MW. MW

In the rural areas, the Rural Electrification Board (REB) could supply barely half of the total demand which was around 2, 400 MW MW per day. In the capital city, the demand stood at around 1, 400 MW while the supply amounted to 650 MW. MW As a result, load-shedding is unavoidable for the time being. But situation is improving very fast. *MW is Megawatt which is a unit of power to measure the output of a power station.
