Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency.

One of the celebrations in Vietnam that holds a special place is the Mid-Autumn Festival, also known as Tet Trung Thu. This festival is traditionally celebrated on the 15th day of the 8th lunar month, which usually falls in September.

The Mid-Autumn Festival is a joyous occasion that is particularly cherished by children and families. It is a time when people gather together to appreciate the beauty of the full moon, enjoy colorful lanterns, and engage in various festive activities.

One of the highlights of the Mid-Autumn Festival is the custom of carrying and parading lanterns. Children and adults alike craft and decorate lanterns in various shapes and sizes, often featuring popular characters from folklore or modern cartoons. The lanterns illuminate the night sky, creating a magical and enchanting atmosphere.

Another significant aspect of the festival is the tradition of lion and dragon dances. These captivating performances involve dancers manipulating large, vibrant lion or dragon puppets to the beat of drums and cymbals. It is believed that these dances bring good luck and ward off evil spirits.

One of the most delightful aspects of the Mid-Autumn Festival is the abundance of mooncakes. These round pastries are filled with various delicious ingredients like sweet bean paste, lotus seed paste, or salted egg yolks. Mooncakes are exchanged among family members, friends, and business associates as a symbol of unity and good wishes.

The Mid-Autumn Festival also provides an opportunity for families to come together and enjoy a festive meal. Relatives gather to share a delicious feast that often includes traditional dishes like sticky rice, fruits, and other seasonal delicacies.

What makes the Mid-Autumn Festival memorable is the sense of community and togetherness it fosters. The celebration brings people of all ages and backgrounds together, promoting unity and harmony. It is a time when families bond, children indulge in joyful activities, and cultural traditions are passed down from one generation to another.

Overall, the Mid-Autumn Festival in Vietnam is a delightful and heartwarming celebration that showcases the rich cultural heritage and the strong sense of community in the country.

When you flip on a light switch, the energy that brightens your light bulb may come from one of several potential energy sources. Different energy sources have varying advantages and disadvantages that don't just affect your utility bill but that may also have a global impact on air quality and environmental degradation.

Wind Energy

Giant wind turbines have begun to appear across North America. As wind hits the turbines, they begin to spin, and the resulting spin generates electricity that can power businesses, homes and other outfits. It provides energy without emitting greenhouse gas emissions. It's also very low-cost in the long run, as the U.S. Department of Energy estimates it to be one of the cheapest forms of renewable energy available, and it's inexhaustible as well.

However, some anti-wind activists argue that wind turbines are ugly, noisy, and dangerous to local bird species that may fly into the turbines, according to Middlebury Schools.

Solar Energy

Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency. Fossil Fuels

Fossil fuels like coal and oil are the most widely-used energy source in the world. It's typically the most plentiful, easily accessible and cheapest form of energy, according to Iowa Public Television.

However, Southern Polytechnic State University warns that fossil fuels are limited and will run out one day. Fossil fuels also endanger the environment due to the mining process and the greenhouse gas emissions produced while burning the fuel. Additionally, they may contribute to harmful side effects like air pollution and acid rain.

Biofuels

Biofuels are made from corn, sugarcane and other crops. Ethanol, widely used as a gasoline additive for powering cars, is a biofuel. It's renewable, grown domestically for greater energy security, and often produces less greenhouse gas emissions when burned, according to the National Center for Environmental Economics.

Unfortunately, growing the crops needed for biofuel may pollute the earth's soil and waterways due to farming processes and side effects like fertilizer runoff. Using crops for fuel may also use up vital food crops, and this can drive up global food prices.
