The festival I participated and remembered the best is Holi Festival in India. It took place at the end of February last year. The fesstival is to welcome spring and to fight against the evils. Participating in the local people and I threw colourful powder to one festival, Ihad a chance to play, dance and sing. The another, and danced under water sprinklers. I had a wonderful vacation there. If having a chance, I still choose to go to India and enjoy the Holi Festival once again.

In today's life, science and technology are increasingly developing and bringing many benefits to people. It keeps people up to date with the latest and most useful information and reality today it helps people about how Covid's character in the world is going on. It also helps people learn things that people have never known and many other benefits so science and technology are indispensable in human life.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

No longer is solar energy a fringe energy source, useful only in sunny regions or for charging portable electronics. Thanks to the huge drop in solar component costs over the last few decades and several innovations in materials and production, solar is rapidly becoming an accessible and affordable option for home power.

The cost of solar modules has fallen some 75 percent just since the end of 2009, the International Renewable Energy Agency reports. Solar energy has hit grid parity in a number of markets, including many of the top cities in the U.S. where solar electricity beats out grid prices. And because of new solar financing options such as solar leasing, more home and business owners can find a solar solution that works for them. For those who can't have solar on their own roof but still want the benefits of clean electricity from the sun, community solar programs are an accessible and affordable option.

There are some tips to save power which I think are very easy to apply. Firstly, we should use energy saving light bulbs in our house. It will help us to reduce our electricity bill. Secondly, we should use public transport if we need to go long distance. We can use bicycles for short distances. I think it is good for our health and economical. And remember, before going to bed, we should turn off all lights and other unused electrical devices. It's an easy way to save our planet.

- What you should do to save energy

With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.

To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.

Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.

Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.

In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.

We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.
