Without new breakthroughs, producing much more biofuel than we do today might be a net-negative for the climate—and would definitely raise our fuel prices. September 20, 2021. When we burn fossil fuels, we take carbon that had once been trapped safely underground and release it into the atmosphere.
In countries like the UK and across Europe, renewable energy has taken a significant share of the market, with 37% of Britain''s electricity coming from renewable sources last year. Getty Images
Here are five reasons why accelerating the transition to clean energy is the pathway to a healthy, livable planet today and for generations to come. 1. Renewable energy sources are all...
If we are serious about making the transition to a low-carbon global energy system we have a fantastic opportunity in front of us. Scaling up renewable energy systems doesn''t only have the direct benefit of more low-carbon energy, but has an indirect side effect that is even more important: cheaper energy.
A green recovery from the COVID-19 pandemic would have helped countries to build back better while driving economic growth and job creation. But the latest Renewables 2022 Global Status Report paints a different picture. According to the report, the global energy transition the world had hoped for is simply not happening.. The rebound in economic activity
by Kevin Stark There are two major categories of energy: renewable and non-renewable. Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The
Renewable energy at home - such as solar panels on the roof - can help save energy costs but also reduce a little our impact on the environment in terms of climate change. With such a win-win solution, why are we not all making the switch, asks EMILY FOLK
The problem is that we normally don''t use logic to make the decision which electricity source to use. We want it all. We want electricity for the whole world, at low cost, at low environmental impact, as soon as possible, with high return for the companies, with large local economic growth, with high shareholder value, easy to use for
The main types of renewable energy are wind, solar, hydroelectric, tidal, geothermal and biomass. Read on to discover the pros and cons of each of these renewable energy sources. One of the main benefits of most renewable energy sources is that they don''t release carbon dioxide or pollute the air when they are used to produce electricity or heat.
But we do have an alternative: renewable energy. This means primarily wind and solar energy, although other energy sources (e.g., geothermal) will also play a role. Non-renewable energy sources such as nuclear could provide another source of climate-safe energy. The amount of renewable energy available is almost unfathomable.
But we do have an alternative: renewable energy. This means primarily wind and solar energy, although other energy sources (e.g., geothermal) will also play a role. Non-renewable energy sources such as nuclear could
Renewable electricity is becoming cheaper than coal-fired power. Petr Josek/Reuters 4. Stable renewable electricity is not hard. Balancing renewables is a straightforward exercise using existing
Next, there are 2 more factors that matter why we aren''t using just green energy. visual pleasantness is a thing in many places. For wind power you''d need to place those "wind mills". However you''d be polluting nature''s visual. This is why wind parks are often placed in the seas or in locations where they don''t obstruct the visuals.
Countries around the world are exploring ways to transition away from fossil fuels. The transition, prompted by carbon emissions that exacerbate climate change, is vast and includes renewables such as solar,
A pair of 500-foot smokestacks rise from a natural-gas power plant on the harbor of Moss Landing, California, casting an industrial pall over the pretty seaside town. If state regulators sign off
Why don''t we use 100% renewable energy in Singapore? In a bid to reduce carbon emissions and mitigate climate change, countries around the world are shifting towards renewable energy to reduce their dependence on fossil fuels. But what about Singapore? As a small country, there are inherent limitations to what we can do to reduce emissions.
Traditional energy sources, such as coal or oil, are non-renewable, meaning they are finite and we will one day use up the earth''s supply. This is obviously an issue, as the entire infrastructure of our planet currently revolves around humans using vast quantities of these substances, which take thousands, or in some cases, millions of years
In practical terms, the world will need to install more than 1,200 gigawatts of renewable energy capacity annually by 2030 to meet our goals. This should spark a sense of urgency. The pathway to accelerating progress remains viable, but
After millions of protesters marched around the globe to demand action on climate change, we more closely examine what policies they are proposing. Miles O''Brien joins William Brangham to
Some studies also find costs for future renewable electricity to be lower than present fossil-fuel costs, in the likely event that costs fall as we build more renewable energy systems and get
In any discussion about climate change, renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That''s because renewable energy sources, such as solar and wind, don''t emit carbon dioxide and other greenhouse gases that contribute to global warming. Clean energy has far more to
The poor need more energy, and much of it will be clean energy which is already viable. It''s the last fraction of energy that is hard to keep fossil-free. It can be done – at a cost.
So, why don''t we use renewable energy more often? Let''s start by taking a look at the main drawbacks of renewables. 1. Renewable Energy Can Be Expensive. With an endless supply of renewable resources, we have the potential to power the earth from clean energy alone. The main obstacle to this is the overall cost of renewable energy.
WWF is working to help promote a clean energy transformation that is aligned with nature and people, ensuring we all have the energy we need, without it costing the earth. Leaders at COP28 must take action so that all countries can agree to phase out fossil fuels and transition to renewables before 2050.

At least 29 U.S. 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
Most renewable energy resources are clean, because they do not produce any pollution and cheap because their energy supplies do not have any cost. Hydroelectric power stations, as well as tidal
by Kevin Stark There are two major categories of energy: renewable and non-renewable. Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The advantage of these non-renewable resources is that power plants that use them are able to produce more power on demand. The non-renewable energy
Hydropower, or hydroenergy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants. The falling water rotates blades of a turbine, which then spins a generator that converts the mechanical energy of the spinning turbine into electrical energy. Hydroelectric power is a significant
