Ko phải mình làm đâu!!!!!!
Solar energy is a renewable source of energy because it comes from the sun. It's clean and safe but it's unpopolar now.
Ideally, what I’d like to do is helping other people, so I’m volunteering at an old folks’ home.
I had been longing for a meaningful experience, and I finally found it there.
What I really loved about going there was talking about all sorts of things with the people I met.
Some had traveled a lot and others had spent their whole lives in my little town. Even so, all of them had gone on such incredible journeys, which included: raising kids, learning skills, and overcoming challenges.
To be honest, I’ve traveled to the far most corners of the world and been on the most incredible journeys, through the stories that my friends have told me, both young and old. It’s both peaceful and fulfilling and I wouldn’t trade it for anything, neither would my friends because they know I’ll always be here for them when they return…
Advantages of renewable energy
The first advantage of renewable energy is that it can be renewable, has an extremely large reserve, can be endless. Forms of energy such as solar, wind, geothermal, ocean waves, rain... are available and free to use, without fuel costs. Biomass energy also has large reserves and low fuel costs. Compared to traditional energy sources such as coal, oil, natural gas, which are increasingly depleted, only meeting human energy needs for about 50-70 years, this advantage is a strength. outstanding.
The second advantage of renewable energy is that it is abundant and can be widely exploited in all different areas of the earth. For example, with solar energy, people can exploit it anywhere, as long as there is sunlight, it can be used to generate heat to make hot water, heating, and generating electricity through the system. Solar power with solar panels… Or with wind energy, this energy source has been used for hundreds of years to move sailing boats, hot air balloons, windmills for irrigation systems. … or the current trend is to produce electricity from wind in many countries around the world.
Despite many great advantages, renewable energy also has some disadvantages, such as:
Due to the influence of nature, renewable energy is less stable than traditional energy sources. Solar energy can only be exploited during the day on sunny days, and at night or on cloudy and rainy days, the system will not work. Or with wind energy, wind turbines can only generate electricity at times when the wind speed is in the range of 4-25 m/s. Wind speed must be at least 4 m/s for the wind turbines to start running smoothly and generate electricity, but if it exceeds 25 m/s, the turbines will stop working to avoid damage in windy conditions. strong.
Requires advanced technology and high cost is also a drawback of renewable energy. To take advantage of renewable energy sources to generate electricity, it requires advanced technology and relatively high investment costs. Currently, the cost of electricity generation from renewable energy is generally higher than the cost from fossil energy. However, the development of renewable energy in the global trend has helped to reduce costs and increase efficiency, gradually improving this shortcoming.
