In our society, almost everything powered is because of electricity. Electricity has been the main source of energy since the 1800’s. As more and more people are realizing the substantial, irreversible damage of fossil fuels, and that the cost of electricity is rising, they are seeking alternatives. Eventually, fossil fuels will run out. As opposed to fossil fuels that are un-renewable, you cannot run out of solar power. According to NASA, we have the sun for another 6.5 billion years! Our sun, the center of our universe is roughly 27 million degrees. Although only a little bit of those rays reach us, it is still enough to power the whole world. There are 3 types of solar panels: Monocrystalline, the most efficient and most expensive, Polycrystalline, the most common, a little less efficient, and a lot less expensive, and Amorphous Silicon or “Thin Film”, the cheapest, not effected by shading, but their efficiency is lowest. On your average day, the sun shines about 1,000 watts of energy per square meter, and that is more than enough energy to power our electricity needs. There are lots of pros and cons facing this controversial subject. Fossil fuels are easy, and standard, where as no one really knows anything about solar energy just yet. Fossil fuels will run out eventually, it’s time to learn. Solar energy is renewable, and abundant. “The surface of the earth receives 120,000 terawatts of solar radiation – 20,000 times more power then what is needed to supply the entire world.” As well as being renewable, and abundant, it is sustainable. There will be no way to over consume solar energy because sustainable energy sources only meet the needs of the present. The next is clear, environmental friendliness. Although with manufacturing, transporting, and installing come emissions, the damage is minuscule compared to the damage that non-renewable energy sources have on our earth. “It is clear that solar energy reduces our dependence on non-renewable energy sources. That is an important step in fighting the climate crisis.” xpensive, and Amorphous Silicon or “Thin Film”, the cheapest, not effected by…
Solar Energy ( Introduction )
-Sunlight is a renewable energy
source which can be converted
light energy into electric energy
by solar panels.
-Solar power is energy from the
sun.. Solar energy has been
looked upon as a serious source
of energy for many years
because of the vast amounts of
energy that are made freely
available, if we use our modern

What is Solar Energy
The sun has produced energy for as long as the earth has been around.
Solar energy is the sun’s rays, (solar radiation) that reaches the Earth. It is
the radiant light and heat from the sun that has been harnessed since ancient
times. It is also one of the of the many renewable energy sources available
to man, but for now cannot replace fossil fuels 100%.
Solar energy can be converted to electricity. This is done in two ways.
One, by using Photovoltaic…
B) Only 60% of gas produced energy of electricity which was sent to the power grid and the remaining energy was lost in the form of heat due to the blades having to overcome air resistance and also the friction of the turbines.
C) Wind energy is less efficient (even when running at their optimum wind speed) because There's friction between all the moving parts, the generator or alternator aren't 100% efficient, and the energy is lost at the rotor blade friction and drag, gearbox losses, generator…
In today’s society, energy is needed in order to provide for a modern way of living. Most people need it for cooking, transportation, and even communication. As energy is becoming more and more necessary, many people are starting to turn toward a cleaner power solution, like solar energy. Solar energy is a very effective solution to obtain energy because it is great for the environment and is becoming widely available.
Every day the sun is shining and giving the Earth warmth…
out many ways to use all kinds of energy to power our everyday products. Today there are many discoveries of different energy sources that have helped us greatly. We have now started to use alternative energies to help with the depleting resources. One of these energies is solar energy. Even though this alternative has helped with the conservation of resources, this has become a huge cost and toll on the economy that has affected it greatly. Solar power using solar panels has become a bigger cost than…
Making solar energy Economical
Solar energy is sustainable since the sun cannot be depleted. It exists every day unless when it is cloudy. However, when it is cloudy stored energy from the previous sunny days can be used. Solar energy is also environmentally clean. Other sources of energy cannot be compared to solar. For example, fossil fuels such as natural gas and oil can be depleted. Coal, on the other hand, exists in high quantities but causes air and water pollution. On the contrary…
Sun, wind currents, and plant-life of many varieties are the most important energy choices for our new planet. The sun is important because we can use solar energy to power most of our needs instead of using electricity that uses terrible fossil fuels. As stated by the power point in our class, “Passive solar heating uses solar energy to heat buildings without the use of equipment. Savings can be as much as 50% of heating costs.” Not only will we be saving our environment from the bad fossil fuels…
Applications of Solar Energy
Solar Energy is the wave of the future. Its use has increased tremendously over the last decade. It is used in many different places and seems to be replacing the traditional methods of obtaining energy at an astounding rate. It’s really no wonder why we would embrace the concept of Solar Energy. There are various ways this energy is used and even more way in which it has benefited today’s society. Solar energy stands alone in its own class of sun powered energy. However…

Solar energy is “energy source that involves tapping the radiant light energy that is emitted by the sun and converting it into electricity.” 1 The conversion of solar energy into electricity is starting to be more popular as the year’s progress, as it should be used more around the world. This essay will cover what the land has to offer and how we are using it, how it affects us Canadians and the world, what…
Solar Panels—The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity throughout the day.
Inverter—This device converts the DC electricity generated by the solar panels into the alternating current (AC) electricity.
Electrical Panel—The AC electricity is sent from the inverter to your electrical panel to power your lights and appliances with solar energy. The electrical panel is often called a "breaker box."
