Watts Up with Renewable Energy? The cleaner and greener energy of the future!
By Alejandro Acevedo on February 8th, 2018 Solar power converts the energy from the sunlight into electricity, this electricity is received by the solar panels that are placed all around the world. What makes the solar power? Well solar panels are powered by PV’s that convert the sun rays into electricity and power TV’s, charge phones and be able to play videogames. The way that the solar panels work is by placing them outside to get sun. The solar panels receive photons, particles of light to create the energy. The solar panels been used more now, probably you have one in your house or someone nearby. By using solar panels we do save a lot of energy in the world, but we cannot be 100% powered by solar panels, the sun does not give us energy for the whole day. When the sun sets, the solar panels stop generating energy. If we need energy at night, we have to go with another resource.

This is a diagram depicting how our sun is made up and its layers within
What makes up our Sun? By Marie Ramos on February 8th, 2017 Earth’s sun was approximately born 4.6 million years ago by a celestial event called the Big Bang. The Big Bang also created the other celestial objects that can be found within our universe. In our galaxy, The Milky Way Galaxy, the sun is at the center producing a heliocentric system, where everything in our systems revolves around our Sun. The Sun made up of six layers, each of which has its own function that keeps the Sun alive and also keeps our solar system warm and filled with light. The inner layers of the sun include the core, radiative zone, and the convection zone. The core is where the Sun’s energy is stored, light and heat is produced, and where the process of fusion occurs. The radiative and convective zones is where the energy from the core radiates out of in the form of radiation and this process takes about a several hundred thousand years in order for the radiation to disperse out.
The outer layers of our sun include the photosphere, chromosphere, and corona. These outer layers of the sun are what scientists are able to observe under specific conditions and with highly specialized equipment. These outer layers are very hot in temperatures, averaging around several millions degrees fahrenheit and is also where light is emitted. Sun spots can also be seen on the photosphere layer of the sun and these sunspots appear from time to time and are typically much cooler surfaces on the sun.
Solar Wind By Jamie Segura on February 8th, 2017 The wind changes based on where on the sun it comes from and how quickly it is rotating. The velocity of the solar wind is higher over coronal holes, reaching speeds of up to 500 miles (800 kilometers) per second. The temperature and density over coronal holes are low, and the magnetic field is weak, so the field lines are open to space. These holes occur at the poles and low latitudes, and reach their largest when activity on the sun is at its minimum. Temperatures in the fast wind can reach up to 1 million degrees F (800,000 C). As the wind travels off the sun, it carries charged particles and magnetic clouds. Emitted in all directions, some solar wind is constantly going around our planet, with interesting effects. The force of the wind stretches out the magnetic field so that it is smooshed inward on the sun-side and stretched out on the night side. Sometimes the sun spits out large bursts of plasma known as coronal mass ejections (CMEs), or solar storms. More common during the active period of the cycle known as the solar maximum, CMEs have a stronger effect than the standard solar wind. When the solar wind carries CMEs and other powerful bursts of radiation into a planet's magnetic field, it can cause the magnetic field on the back side to press together, a process known as magnetic reconnection. Charged particles then stream back toward the planet's magnetic poles, causing beautiful displays known as the aurora borealis in the upper atmosphere. Though some bodies are shielded by a magnetic field, others lack their protection.
Here in this picture (not to scale) we can see how the tilt of the Earth affects our seasons, maybe not the Sun.
How Does The Sun Cause Seasons on Earth? By Joyce Mendoza on February 8th, 2018 In reality, the Sun doesn’t causes seasons on Earth. The Earth’s tilt causes seasons. In this article, I will explain how the sun has a big influence in our seasons. The Earth is in the Goldilock Zone. That means that the Earth is in a zone where it is not to close, nor not to far from the sun. This is one of the key point in making seasons. People thought that we have Summer because the Earth is closer to the sun, and we have winter because the Earth is far away from the sun. It is winter in the Northern Hemisphere, but if you ask a person living in Australia how’s the weather, they will tell it’s so hot. This proves that the distance between the Earth and the Sun don’t cause the seasons. The Earth is tilted. The amount of sunlight is different based on how the Earth is tilt. The changing height of the Sun in the sky, along with the changing amount of sunlight received during the day, causing seasons.
