The difficulty is achieving the technology.
Two advantages of using renewable energy to generate electricity.
Programs like scotland s saltire prize.
Two common examples of this type of energy are solar power and wind power.
The primary advantage of renewable energy is that fewer potentially harmful emissions are released into the atmosphere.
Although renewable energy is built on an infrastructure that uses fossil fuels the emissions cost savings of renewables occurs quite rapidly.
Marine energy projects currently generate an estimated 500 megawatts of power less than one percent of all renewables but the potential is far greater.
It is a clean form of energy to use.
Moreover the costs of renewable energy technologies have declined steadily and are projected to drop even more.
Geothermal power hydropower biomass and tidal power are additional forms of renewable energy that produce power for our planet right now.
However the logistics and overall energy balance may defeat it in that a lot of energy.
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators.
Burning biomass for generating electricity has some appeal as a means of indirectly using solar energy for power.
The energy generated through hydropower relies on the water cycle which is driven by the sun making it a renewable power source making it a more reliable and affordable source than fossil.
It is driven particularly by eu energy policy which classifies it as renewable and ignores the co 2 emissions from burning the wood product.
For example the average price to install solar dropped more than 70 percent between 2010 and 2017.
Renewable energy is energy that comes from sources that replenish themselves over short periods of time.
For the most part renewable energy sources also provide clean energy or energy that emits few greenhouse gases or pollutants.
The cost of generating electricity from wind dropped 66 percent between 2009 and 2016.
But it s also important to be aware of the downsides for example needing certain weather conditions to generate energy.
Costs will likely decline even further as.
For this reason many policy experts and scientists advocate renewable energy sources over traditional fossil fuels.
