We need to use renewable energy sources to reduce greenhouse gas emissions and combat climate change, as non-renewable sources like fossil fuels contribute significantly to global warming. Renewable energy sources, such as solar, wind, and hydro, are sustainable and abundant, helping to ensure long-term energy security. Additionally, transitioning to renewables can create jobs, stimulate economic growth, and reduce air and water pollution, leading to a healthier environment.
What else can I help you with?
What are the potential uses and limitations of renewable energy sources?
Renewable energy sources, such as solar, wind, and hydro, offer sustainable alternatives to fossil fuels, helping to reduce greenhouse gas emissions and combat climate change. They can provide energy security and create jobs in green technology sectors. However, limitations include intermittent energy supply, high initial costs, and the need for significant infrastructure investment. Additionally, some renewable sources can have environmental impacts, such as land use changes or effects on local ecosystems.
When and how was biomass energy discovered?
Biomass energy has been utilized since ancient times, as early humans burned wood and other organic materials for heat and cooking. The formal recognition of biomass as a renewable energy source gained momentum in the late 20th century, particularly during the 1970s energy crisis when the need for alternative energy sources became apparent. Research and development in biomass technologies have since evolved, leading to modern applications such as biofuels and biogas. Today, biomass is considered a key component of the renewable energy sector, contributing to sustainable energy solutions.
Why do we need to improve sources of energy that are not fossil fuels?
since fossil fuels can be found almost anywhere in the world we need to improve sources of energy so that they are around the world............
Can gas provide lots of energy for the future?
Yes, natural gas can provide significant energy for the future due to its abundance, efficiency, and lower carbon emissions compared to coal and oil. It is often seen as a transitional fuel that can support the shift to renewable energy sources while meeting current energy demands. However, concerns about methane emissions and the need for a more sustainable energy mix may impact its long-term role in the energy landscape. Balancing gas use with the expansion of renewables and energy efficiency will be crucial for a sustainable energy future.
Why is it important to develop alternate energy source?
We need to use differant energy soureces that are renewable. THis is because at the moment most of the enrgy that we use is unrenewable, coal, oil, petrol etc. It takes millions of year to create and is burnt in a matter of minuetes. We need energy that is renewable so we can supply it quickly when we need it because all nonrenewable enrgy's are running out. Only in 1 million yearsif a fish dies now will it be compatable to turn into fuel. Wind power, solar power, movement energy are all renewable. THis is why it is very important we use those things. Hope this helped :-) Lucy Year 7
What is the need for renewable energy in today's scenario?
In today's scenario, all other sources depleting. Hence, renewable sources should be used.
How are energy sources renewable?
Renewable energy resources are always there. We just need to harness them.
What renewable energy sources do not need water?
wind powersolar power
Why cant we get all the power we need from renewable energy sources right now?
We are still dependent on fossil fuels due to factors such as the intermittency of renewable sources like solar and wind energy, limitations in energy storage technology, and the high cost of transitioning existing infrastructure to renewable sources. Additionally, some regions may lack the necessary resources or infrastructure to fully utilize renewable energy at present.
Do you need renewable energy and non renewable energy?
Yes, a mix of both renewable and nonrenewable energy sources is needed to meet current energy demands. Renewable energy sources like solar, wind, and hydropower are more sustainable and environmentally friendly, while nonrenewable sources like fossil fuels are still necessary for providing constant supply and meeting peak energy demands. Transitioning towards a greater reliance on renewable energy is important for reducing greenhouse gas emissions and combating climate change.
What energy source is not a fuel?
Renewable energy sources like solar, wind, and hydropower are examples of energy sources that are not considered traditional fuels, as they generate energy without the need for combustion.
What are renewable sources of energy?
Renewable sources of energy, like solar, wind, geothermal, tidal, hydro/water and biomass, are sources that that are not consumed during their use. When oil is burned it is consumed, finished. It can't be used again. But renewable sources will still be there after we have used them, like the sun, still radiating heat and light for as long as we need them.
Will renewable energy be able to sustain the energy need for the future?
It will have to, in the long term; by definition, the alternatives are not sustainable. People have lived for thousands of years with renewable energy sources; we will somehow have to do this again in the future... or else.
Why should humans have more hydroelectric power?
Humans need more electricity, regardless of source. Hydroelectric and other renewable sources of energy are preferred to energy produced from the burning of fossil fuels.
Why is it important that you increase the use of energy from renewable sources?
Because when you depend on energy sources which are not renewable and they run out, you are (for lack of a better descriptive and effective term) screwed. However, dependence on renewable sources means you will hypothetically never run out of energy and renewable sources are typically cheap; the only cost is the initial setup and maintenance.
Why don't and we use more renewable energy sources?
The transition to renewable energy sources faces challenges such as high initial costs, infrastructure limitations, and technological constraints. Additionally, existing fossil fuel industries are deeply entrenched, making it difficult to shift investments and policy focus. There is also a need for improved energy storage solutions to manage the intermittent nature of renewable sources like solar and wind. Lastly, regulatory and political factors can hinder the momentum towards broader adoption of renewable energy.
What does it mean when an energy resorce is said to be non renewable?
Renewable energy can be renewed in a short time I.e. Wind power. Non renewable energy takes a long time, ususally millions of years, to become usuable again I.e. Fossil Fuels.
