California leads the nation in electricity generation from non-hydroelectric renewable energy sources, including geothermal power, wind power, and solar power. California has some of the most aggressive renewable energy goals in the United States.

As of 2011, the electricity mix in the city was made up of 16% non-large hydropower renewables, 30% large hydro, 36% fossil fuels, and 18% nuclear. The City has a goal to have a 100% renewable electricity supply community wide by 2030.

hydroelectric power plants

California utilities partly own and import power from several power plants in Arizona and Utah. In addition, California’s electricity imports include hydroelectric power from the Pacific Northwest, largely across high-voltage transmission lines running from Oregon to the Los Angeles area.

Petroleum. California is the largest consumer of motor gasoline and jet fuel in the nation.

2018 Total System Electric Generation

The water itself is not reduced or used up in the process, and because it is an endless, constantly recharging system, hydropower is defined as a renewable energy by the Environmental Protection Agency. But it’s not considered renewable by everyone.

There are many places around the world with grids that are run almost exclusively on renewable energy. At the national level, at least 30 nations already have renewable energy contributing more than 20% of the energy supply.

Iceland is a country running on 100% renewable energy. It gets 75% of the electricity from hydropower, and 25% from geothermal. The switchover meant the country now has cleaner air due to utilizing renewable sources rather than fossil fuels.

Leading countries in installed renewable energy capacity worldwide in 2020 (in gigawatts)

The US ranks at 10th with a clean energy proportion of less than half that of the UK and nearly three times less that of Germany at 4.32%….Top ten countries with the highest proportion of renewable energy.

Lowest Percentages of Alternative Energy By Country

Three countries use more fossil fuels than the rest of the world combined: China, the United States and India. Together, these countries consume 54 percent of the world’s fossil fuels by weight, according to the Global Material Flow Database developed by the UN Environment Programme.

Texas has consumed the most energy in every year since 1960, the earliest year for which EIA has data. California ranked second in energy use, with a total consumption of 8 quadrillion Btu, about 8% of U.S. total energy use.

The USA

United States

Unsurprisingly, the three largest producers of fossil fuels are China, America and Russia, with Saudia Arabia being the fourth largest producer of fossil fuels over all. And fossil fuel production is a largely non-European affair – only Norway appears in the top 15.

Photosynthesis. Cellular Respiration. Burning fossil fuels.

Storing and utilizing methane can be tricky and poses potential problems that may exacerbate the global warming issue we are currently facing today. It is highly flammable, which increases the risk of combustion given ideal conditions.

High levels of methane can reduce the amount of oxygen breathed from the air. This can result in mood changes, slurred speech, vision problems, memory loss, nausea, vomiting, facial flushing and headache. In severe cases, there may be changes in breathing and heart rate, balance problems, numbness, and unconsciousness.

If methane is to be stripped out of the atmosphere, taking advantage of natural air flow provides a viable solution. Natural processes destroy roughly 10% of the methane in the atmosphere every year6.

When methane is produced from non-fossil sources such as food and green waste , it can literally take carbon out of the air. However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change.

Methane also contributes to the forming of the ozone, decreasing air quality and leading to various health issues in animals, premature human deaths, and reduced crop yields. Ultimately, reducing the amount of methane in the atmosphere will lessen these effects.
