What did I learn from everyone else's presentation?

Tseki - Solar power
From Tseki's presentation, I learned that solar cells require photovoltaic cells in order to operate. Also, solar power panels are good because they have no gas emissions, are a good investment and it is easy to find space accommodations on a small scale. On the larger scale, it creates more jobs because a solar project requires people to build the plants. However, solar power also has some disadvantages. It is an intermittent source because the solar panels can only absorb the sun's heat during the day. Large scale solar power projects can also destroy animal habitats. Not everyone can afford solar power because the materials to make the solar panels are rare and expensive. Even buying batteries to store the energy prove to be expensive.

Saw - Solar power
Photovoltaic is required in solar cells and it is one of the most common renewable energy source. It is cost efficient, meaning it is very cheap to maintain since it only need sunlight and once the solar panels are made, it just needs sunlight to be stored and converted to energy. As there are no space limitations, as many can be made and it will just be more beneficial. However, when the construction of the solar cell and panel is taking place, it will produce global warming and it might damage some natural habitats. Also it is very expensive to make them. Solar power is getting cheaper each year and we are improving its efficiency with technology.

Sonam - Wind energy
Through her presentation, i learned that wind is caused by the rotation of the earth, uneven heating of the atmosphere of the sun and irregularities of the earth's surface. There are two types of turbines: the horizontal axis and the vertical axis wind turbine. Although beneficial, it can be a threat to wildlife and the wind is unpredictable, so it is hard to capture and store amount of energy constantly everyday. By 2040, wind energy will exceed hydropower and be the most used renewable energy source.

Freddie - Wind energy
There are many sorts of objects that can produce energy. Turbines that make electrical energy, wind pumps which makes energy by pumping water, windmills that make mechanical power and sails which use propelling ships. Wind power is solar energy. The turbines use sophisticated technology to catch the wind's energy. There is small, intermediate and large wind turbines. They all produce different amounts of energy per year according to their size. This adds up to the country's GDP and is 100% renewable. However, it disturbs many wildlife creatures like birds. the solutions are that the turbines could be manufactured in isolated areas such as in oceans or in the middle of nowhere.
