SOCIAL MEDIA

                The Influence of Social Media on Teenagers

Social media has become a space where we form and build relationships, form our identities, express ourselves, and learn about the world around us. However, it should be reiterated that like technology in general, the use of social media certainly has good and bad effects on various aspects of its users lives, especially in terms of users' mental health. Considering that social media users are mostly teenagers and at that age is a very important phase for their emotional and psychosocial development.

The existence of social media makes everyone able to communicate even at great distances. Besides being able to make friends with many people. Social media can also be used as a medium of information, whether in education, social, or politics. Finally, social media can also be used for us to share the knowledge we have by posting on social media.

On the other hand, there is a positive impact that can be obtained, there is a negative side from uncontrolled use of social media. Among them, teenagers can experience social disorders, become selfish individuals. And also makes someone addicted and some even experience depression due to their dependence on social media.

So that we can benefit and provide benefits to many people. Social media has both positive and negative impacts. But we can not avoid the development of these technologies. We can only control ourselves how we use it wisely. 

RENEWABLE ENERGY

 

What is renewable energy?

Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. For example, sunlight or wind keep shining and blowing, even if their availability depends on time and weather.

Types of renewable energy source

1. Solar Energy

    Solar, or photovoltaic (PV), cells are made from silicon or other materials that transform sunlight directly into electricity. Distributed solar systems generate electricity locally for homes and businesses, either through rooftop panels or community projects that power entire neighborhoods.

2. Wind Energy

    Wind energy turns a turbine’s blades, which feeds an electric generator and produces electricity.

3. Biomass Energy 

    Biomass is organic material that comes from plants and animals, and includes crops, waste wood, and trees. When biomass is burned, the chemical energy is released as heat and can generate electricity with a steam turbine. 

4. Geothermal Energy

    Earth’s core is about as hot as the sun’s surface, due to the slow decay of radioactive particles in rocks at the center of the planet. Drilling deep wells brings very hot underground water to the surface as a hydrothermal resource, which is then pumped through a turbine to create electricity. Geothermal plants typically have low emissions if they pump the steam and water they use back into the reservoir. There are ways to create geothermal plants where there are not underground reservoirs, but there are concerns that they may increase the risk of an earthquake in areas already considered geological hot spots.

The Advantages of Renewable Energy Resources

1) A Fuel Supply That Never Runs Out

    As the name suggests, renewable energy is created from sources that naturally replenish themselves – such as sunlight, wind, water, biomass, and even geothermal (underground) heat.

2) Cleaner Air and Water

    Renewable energy creates no pollution, waste, or contamination risks to air and water. And while the COVID-19 lockdowns gave us a glimpse of clear skies in major cities all over the world, renewable energy has the potential to make clean air the new normal.

3) Renewable Energy Creates New Jobs

  With an increasing focus on global warming and many governments setting ambitious carbon-reduction goals, one of the surprising renewable energy advantages is that it has quickly become a major source of new job growth.

The Disadvantages of Renewable Energy

1) Higher Capital Costs

2) Electricity Production Can Be Unreliable

3) Energy Storage Is a Challenge

4) It’s Impacted by Environmental Conditions

5) Renewables Still Have a Carbon Footprint
