Renewable energies are energy sources that are alternatives to fossil fuels and can be replenished. Everyday industrialized countries pollute the Earth’s atmosphere with fossil fuel byproducts, like CO2, creating adverse effects such as climate change and global warming. From big businesses on an industrial scale to single individuals we all play a part in pollution, with things ranging from factories to automobiles. This is a big concern, considering many people would like to preserve the earth for generations to come. Due to this fact scientists have started to find new ways to provide cleaner and alternative energies to power the Earth.

The history of using energies dates way back into the neolithic era when early humans started to use coal as an energy source. Since then we have made extensive advancements in the energy field. The biggest advancements being, the advent fossil fuels and renewable energies. Fossil fuels are hydrocarbons, mainly coal, oil or natural gas and are formed from the remains of dead plants and animals.(SCIENCEDAILY). Renewables use earth processes to create energy. The many types of renewable energy sources available to us now are solar power, wind power, geothermal energy, hydropower, and biomass. The top 3 renewable resources are hydropower, wind power ,and solar power.
Hydropower is by far the most used renewable energy. It accounts for over 16 percent of the world 's net electricity production. The most common method of hydropower energy involves the building of dams on rivers and releasing water from a reservoir to drive turbines.(POWERTECH). The second most used and fastest growing renewable energy is wind power. Wind power uses wind to spin a turbine creating electricity. If used in ...

...ility. Renewable energy relies on the weather for its source of power. Hydro generators need flowing water, wind turbines need wind to turn the blades, and solar panels need clear skies and sunlight to collect heat and make electricity.(SOLARSCHOOLS). When these are unavailable we can 't attain energy from them. The current cost of renewable energy technology is also more expensive than fossil fuel technology. This is because it is a newer technology and as such has extremely large capital cost.

Renewable energy is definitely the way to go. There are are a lot of benefits to this system compared to fossil fuels. It is replenishable, stable, produces less pollution, and overall a better choice . If we would to keep the world going for aeons to come and not hand over the earth to the next generation worse off than it is now we need to switch over to renewables.

Energy Sources Essay

- Introduction Electricity is generated by the use of energy. Before going further, it will be necessary to talk briefly on what energy is all about. In this modern day, the standard scientific definition of energy is the capacity to do work, which means ability to move an object against a resisting force (Boyle 2003). According to (Beggs 2009) a physicist or an engineer will best describe energy in a form of an illustration. I.e. consider a mass of 1kg which is raised 1m above a surface on which it was originally resting....   [tags: Energy ]
