September 2, 2022, 1:27 p.m. ET — On August 31, California lawmakers passed an aggressive climate package that included $54 billion in renewable energy and sustainability measures. The legislation also codifies new benchmarks for 2035 and 2040 to ensure the state meets its goal of 100 percent clean electricity by 2045. Governor Newsom is expected to sign the bill into law this month.
Renewable energy, also called alternative energy, useful energy produced from renewable sources such as the sun (solar energy), wind (wind energy), rivers (hydroelectricity), hot springs (geothermal), tides (tidal energy) and biomass. (biofuel).
At the start of the 21st century, around 80% of the world’s energy supply is produced from fossil fuels such as coal, oil and natural gas. Fossil fuels are a finite resource; Most estimates indicate that proven oil reserves are large enough to meet global demand at least until the middle of the 21st century. Burning fossil fuels has a number of negative environmental consequences. Fossil fuel power plants emit air pollutants such as sulfur dioxide, particulate matter, nitrogen oxides and toxic chemicals (heavy metals: mercury, chromium and arsenic), and mobile sources, such as vehicles fossil fuels, emit nitrogen oxides, carbon. Monoxide and particles. Exposure to these pollutants can cause heart disease, asthma and other health problems in humans. Additionally, emissions from burning fossil fuels are responsible for acid rain, which causes many lakes to acidify and result in damage to aquatic life, leaf destruction in many forests, and smog production. in or near many urban areas. . In addition, burning fossil fuels releases carbon dioxide (CO

On the contrary, renewable energy sources accounted for almost 20% of global energy consumption at the start of the 21st century, mainly thanks to the traditional use of biomass such as wood for heating and cooking. In 2015, around 16% of total global electricity came from large hydropower plants, while other types of renewable energy (such as solar, wind and geothermal) accounted for 6% of all electricity generation . Some energy analysts consider nuclear power a form of renewable energy due to its low carbon emissions; Nuclear energy produced 10.6% of the world’s electricity in 2015.

Growth in wind power exceeded 20% and photovoltaics grew by 30% annually in the 1990s, and renewable energy technology continued to develop throughout the early 21st century. Between 2001 and 2017, installed wind capacity worldwide increased 22 times, from 23,900 to 539,581 megawatts. Photovoltaic capacity is also being developed, increasing by 50% in 2016 alone. The European Union (EU), which produced around 6.38% of its energy from renewable sources in 2005, adopted in 2007 a target to increase this figure to 20% by 2020. In 2016, around 17% of EU energy came from renewable resources. . . The targets also include plans to reduce carbon dioxide emissions by 20% and ensure that 10% of all fuel consumption comes from biofuels. The European Union is also on track to meet its target by 2017. Between 1990 and 2016, EU countries reduced their carbon emissions by 23% and increased biofuel production to 5.5% of all the fuels consumed in the region. In the United States, many states are responding to concerns about climate change and reliance on imported fossil fuels by setting targets for increasing renewable energy over time. For example, California requires its major utilities to generate 20% of their electricity from renewable sources by 2010, and by the end of that year, California utilities were less than 1% objective. In 2008, California increased this requirement to 33% by 2020, and in 2017 the state increased its goal of using renewable energy to 50% by 2030. what renewable energy?

US solar and wind generation is running at full capacity and is integrated into the national power grid without compromising reliability. This means that renewables are increasingly replacing “dirty” fossil fuels in the electricity sector, offering the benefit of reducing carbon emissions and other types of pollution. But not all energy sources marketed as “renewable” are good for the environment. Biomass dams and large hydroelectric plants create difficult trade-offs when considering impacts on wildlife, climate change, and other issues. Here’s what you need to know about the different types of renewable energy sources and how you can use this emerging technology in your home. What is renewable energy? Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly being renewed. For example, sunlight and wind continue to shine and blow, although their availability depends on weather and weather. While renewable energy is often seen as a new technology, harnessing the power of nature has long been used for heating, transportation, lighting and more. The wind created boats to navigate the ocean and windmills to grind wheat. The sun brought warmth during the day and helped keep the fire going until dusk. But over the past 500 or so years, humans have increasingly turned to cheaper and dirtier energy sources, like coal and frack gas. We now have innovative and less expensive ways to capture and store wind and solar power, making renewables an increasingly important source of electricity, accounting for more than 12% of state power generation. -United. Renewable energy expansion is happening on both a large and small scale, from wind farms offshore giants to solar panels on the roofs of homes, which can resell electricity to the grid Even entire rural communities (in Alaska , Kansas and Missouri) depend on renewable energy for heating and lighting. renewable energy continues to grow, a major focus will be modernizing the US electric grid, making it smarter, safer and better integrated across the region. and coal. Non-renewable energy sources exist only in limited quantities. When we pump gas into a station, we are using a finite resource distilled from crude oil that has existed since prehistoric times. Non-renewable energy sources also tend to be present in some parts of the world, so some countries have more of them than others. Instead, each country has access to sunlight and wind. Prioritizing renewable energy can also improve national security by reducing the country’s dependence on exports from countries rich in fossil fuels. Many non-renewable energy sources can harm the environment or human health. For example, oil drilling may require surface mining in Canada’s boreal forest; Hydraulic fracturing technology can cause earthquakes and water pollution; And coal-fired power plants pollute the air. In addition, all these activities contribute to global warming. Types of Renewable Energy Sources Solar Energy Humans have used solar energy for thousands of years – to grow plants, heat and dry food. According to the National Renewable Energy Laboratory, “more of the sun’s energy hits the Earth in an hour than the entire world uses in a year.” Today, we use sunlight in many ways – to heat homes and businesses, to heat water, and to power electrical appliances. East Austin, Texas Rooftop solar panels Roschetzky/iStock Solar or photovoltaic (PV) cells are made of silicon or other materials that convert sunlight directly into electricity. Distributed solar systems generate electricity locally for homes and businesses, whether through rooftop panels or community projects that power entire neighborhoods. A solar farm can generate enough electricity for thousands of homes, using mirrors to focus sunlight onto several acres of solar cells. Floating solar farms – or “floating voltaics” – can be an effective use of wastewater treatment facilities and ecologically insensitive water bodies. Solar power provides nearly 3% of electricity generation in the United States (some sources estimate it will reach nearly 4% by 2022). But 46% of all new generation capacity will come from solar power in 2021. Solar power systems do not produce air pollutants or greenhouse gases. , and as long as they are installed responsibly, most solar panels have an environmental impact beyond the manufacturing process. We have come a long way from the old windmills. Today the turbines are as tall as skyscrapers
