Renewable Energy Current Events

Renewable Energy Current Events – Renewable electricity capacity additions set another record in 2021, with biofuel demand nearing pre-Covid levels despite ongoing logistical challenges and rising prices. However, the Russian Federation’s invasion of Ukraine (hereafter “Russia”) is sending shockwaves through the energy and agricultural markets and causing an unprecedented global energy crisis. Governments in many countries are trying to protect consumers from high energy prices, reduce dependence on Russian resources and propose policies to accelerate the transition to clean energy technologies.

Renewable energy has great potential to reduce prices and dependence on fossil fuels in the short and long term. Even as the cost of new solar and wind services has risen, reversing a decade of declining costs, prices for natural gas, oil and coal have risen much faster, further increasing the competitiveness of renewable electricity. However, how quickly renewables can replace fossil fuels will depend on many uncertainties and many factors. Will renewable electricity sources withstand this global energy crisis and continue to expand rapidly despite new political and macroeconomic challenges? At the same time, biofuel demand growth faces significant headwinds due to both lower transport demand growth and higher biofuel prices. Will demand continue to grow at historic rates?

In any discussion of climate change, renewable energy is often at the top of the list of changes the world can implement to offset the worst effects of warming. Because renewable energy sources like the sun and wind do not release carbon dioxide and other greenhouse gases that contribute to global warming.

Clean energy advises much more than just being ‘green’. The growing industry creates jobs, makes power grids more robust, expands access to energy in developing countries and helps lower energy bills. All of these factors have contributed to the renaissance of renewable energy in recent years, with wind and solar setting new records for electricity generation.

Gap Between Renewable Energy And Power Demand: Oil, Gas, Coal Needed

For nearly 150 years, people have relied on coal, oil and other fossil fuels to power everything from light bulbs to cars and factories. Fossil fuels are embedded in almost everything we do, and as a result, greenhouse gases from burning these fuels have reached historically high levels.

Greenhouse gases keep heat that would otherwise escape to space in the atmosphere, while the average surface temperature rises. Global warming is a symptom of climate change scientists now prefer to describe the complex changes affecting the planet’s weather and climate systems. Climate change includes not only rising average temperatures, but also extreme weather events, changing wildlife populations and habitats, rising seas, and a host of other impacts.

Of course, renewable energy sources – like any energy source – have their trade-offs and related controversies. One of them is related to the definition of renewable energy sources. Actually, renewable energy is exactly what you think: it can be used forever or like the US. The Energy Information Administration describes it as “virtually inexhaustible.” But “renewable” does not necessarily mean sustainable, as opponents of corn-based ethanol or large hydroelectric dams often claim. It also excludes other low- or zero-emissions sources it supports, including energy efficiency and nuclear power.

Hydroelectricity: For centuries, people have harnessed the power of river currents, using dams to control the flow of water. Hydropower is by far the largest source of renewable energy in the world, with China, Brazil, Canada, the United States, and Russia being the leading producers of hydropower. Although hydroelectric power is theoretically a clean source of energy that is full of rain and snow, it also has some disadvantages.

Large dams can disrupt river ecosystems and surrounding communities, harm wildlife and displace residents. Hydropower generation is vulnerable to silting, which can compromise capacity and damage equipment. Drought can also cause problems. In the western US, carbon dioxide emissions over a 15-year period were 100 megatons higher than they would normally be, according to a 2018 study, as utilities turned to coal and natural gas to replace hydropower which was lost due to drought. Even full-scale hydropower carries its own emissions problems, as the decay of organic matter in reservoirs releases methane.

Dams aren’t the only way to use water for energy: tidal and wave energy projects around the world aim to capture the ocean’s natural rhythms. Marine energy projects currently generate about 500 megawatts of power – less than one percent of all renewable energy – but the potential is much greater. Programs such as Scotland’s Saltire Award have driven innovation in this area.

Wind: The use of wind as a source of energy began more than 7,000 years ago. Now, wind turbines that generate electricity are spreading around the world, and China, the United States, and Germany are the leading producers of wind power. From 2001 to 2017, cumulative wind power worldwide increased from 23,900 mW to 539,000 megawatts, more than 22 times.

Some people may object to how wind turbines look and sound on the horizon, but wind energy, with its prices falling, is proving to be an undeniably valuable resource. While most wind power comes from onshore turbines, offshore projects are also emerging, notably in the UK and Germany. The first US offshore wind farm opened in Rhode Island in 2016, and other offshore projects are gaining momentum. Another problem with wind turbines is that they pose a danger to birds and bats, killing hundreds of thousands of people every year, not just from glass collisions and other threats like habitat loss and invasive species, as engineers work on solutions. Good. It is safer for wildlife to throw them.

Geothermal News On Paper

Solar Power: From rooftops to utility-scale use, solar power is reshaping energy markets around the world. In the decade from 2007 to 2017, the world’s total installed solar capacity increased by 4,300 percent.

In addition to solar panels that convert sunlight into electricity, concentrated solar power (CSP) plants use mirrors to concentrate the sun’s heat, rather than collecting thermal energy. China, Japan and the United States are leading the solar transformation, but solar energy still has a long way to go, accounting for about 2% of all electricity generated in the United States in 2017. water, heating and cooling.

Biomass: Biomass energy includes biofuels such as ethanol and biodiesel, wood and wood waste, landfill biogas, and municipal solid waste. Like solar energy, biomass is a versatile energy source that can fuel vehicles, heat buildings and generate electricity. However, biomass can create difficult problems.

The Latest In Clean Energy News

Critics of corn-based ethanol, for example, say it competes with the food market for corn and promotes the same harmful agricultural practices that lead to toxic algal blooms and other environmental hazards. Likewise, debate erupted over whether it was a good idea to ship wood pellets from American forests to Europe to be burned for electricity. Meanwhile, researchers and companies are working on ways to more efficiently convert sludge, sewage sludge and other sources of biomass into energy to extract value from material that would otherwise go to waste.

Geothermal: Geothermal energy, which has been used for cooking and heating in some countries for thousands of years, comes from the Earth’s internal heat. On a large scale, underground reservoirs of steam and hot water can be taken from wells that can go a mile or more deep to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences a few meters below ground for heating and cooling. Unlike solar and wind energy, geothermal energy is always available, but it has side effects that must be dealt with, such as the rotten egg smell that can accompany the hydrogen sulfide that is released.

City, state and federal governments around the world are implementing policies to boost renewable energy. At least 29 US states have set renewable energy portfolio standards, which are guidelines that require a certain percentage of energy to come from renewable sources. More than 100 cities around the world currently have at least 70 percent renewable energy, while others have committed to reaching 100 percent. Other policies that can stimulate renewable energy development include carbon pricing, fuel economy standards, and building performance standards. Companies are also making a difference, buying record amounts of renewable energy in 2018.
