3 good things about renewable energy.

Renewable energy often referred to as clean energy comes from natural sources or processes that are constantly replenished. 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. Electricity can be generated using a turbine to drive a generator before distribution. Renewable energy usable energy derived from replenishable sources such as the sun solar energy wind wind power rivers hydroelectric power hot springs geothermal energy tides tidal power and biomass biofuels.

Options for using renewable energy include. In contrast most renewable energy sources produce little to no global warming emissions. For example sunlight or wind keep shining and blowing even if their. 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.

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. 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. All energy sources have some impact on our environment. Several forms have become price competitive with energy derived from fossil fuels.

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. 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. 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. 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.

Ambitious investment in renewable energy and energy efficiency could lead to 63 million new jobs by 2050. 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.
