Using current technologies most ocean energy is not cost effective compared to other renewable energy sources but the ocean remains an important potential energy source.
3 good things about renewable energy.
Electricity can be generated using a turbine to drive a generator before distribution.
In contrast most renewable energy sources produce little to no global warming emissions.
Using a combination of renewable energy options can help meet local government goals especially in some regions where availability and quality of renewable resources vary.
States have set renewable portfolio standards policies that mandate a certain percentage of energy from renewable sources more than 100 cities worldwide now boast at least 70.
Even when including life cycle emissions of clean energy ie the emissions from each stage of a technology s life manufacturing installation operation decommissioning the global warming emissions associated with renewable energy are minimal.
Energy from ocean waves and tides can be harnessed to generate electricity and ocean thermal energy from the heat stored in seawater can also be converted to electricity.
Several forms have become price competitive with energy derived from fossil fuels.
Options for using renewable energy include.
Today more than 11 million people work in the renewable energy sector globally while 3 3 million people work in the energy efficiency industry across the united states and europe alone.
Renewable energy often referred to as clean energy comes from natural sources or processes that are constantly replenished.
At least 29 u s.
However renewable sources such as wind solar geothermal biomass and.
Generating renewable energy on site using a system or device at the location where the power is used e g pv panels on a state.
Renewable energy is also the most economic solution for new grid connected capacity in areas with good resources.
For example sunlight or wind keep shining and blowing even if their.
Fossil fuels coal oil and natural gas do substantially more harm than renewable energy sources by most measures including air and water pollution damage to public health wildlife and habitat loss water use land use and global warming emissions.
Renewable energy costs continue to drop and the levelised cost of electricity is declining for wind power solar photovoltaic concentrated solar power and some biomass technologies.
Ambitious investment in renewable energy and energy efficiency could lead to 63 million new jobs by 2050.
