How much bioenergy will be needed by 2050?
Some research suggests that bioenergy could meet 20 percent of the world’s total annual energy demand by 2050. Yet doing so would require an amount of plants equal to all the world’s current crop harvests, plant residues, timber, and grass consumed by livestock–a true non-starter.
Why is bioenergy important?
Because land and the plants growing on it are already generating these benefits, diverting land—even degraded, under-utilised areas—to bioenergy means sacrificing much-needed food , timber, and carbon storage. Second, bioenergy production is an inefficient use of land.
How many people will be in the world by 2050?
One of the great challenges of our generation is how the world can sustainably feed a population expected to reach 9.6 billion by 2050. Using crops or land for biofuels competes with food production, making this goal even more difficult.
Does bioenergy increase competition?
That said, some forms of bioenergy do not increase competition with food or land, and using them instead of fossil fuels could reduce greenhouse gas emissions. One example is biomass grown in excess of what would have grown without the demand for bioenergy, such as winter cover crops for energy. Others include timber processing wastes, urban waste wood, landfill methane, and modest amounts of agriculture residues.
Does bioenergy remove carbon?
Yet if those plants were going to grow anyway, simply diverting them to bioenergy does not remove any additional carbon from the atmosphere and therefore does not offset the emissions from burning that biomass. Furthermore, when natural forests are felled to generate bioenergy or to replace the farm fields that were diverted to growing biofuels, greenhouse gas emissions go up.
Does bioenergy use land?
It uses land needed for food production and carbon storage , it requires large areas to generate just a small amount of fuel, and it won’t typically cut greenhouse gas emissions. First, dedicating areas to bioenergy production increases competition for land.
Is biofuel a green alternative to fossil fuels?
Biofuels Are Not a Green Alternative to Fossil Fuels. This blog post was originally published in The Guardian on January 29, 2015. Powering cars with corn and burning wood to make electricity might seem like a way to lessen dependence on fossil fuels and help solve the climate crisis. But although some forms of bioenergy can play a helpful role, ...
How do biofuels differ from fossil fuels?

If what’s here is gone, it will take millions and millions of years for more. Then you see the problem.
What are the things that we don't have an alternative source of energy?
Topics. Biomass and bioenergy. Biofuels. Energy.
What is the second generation of bioenergy?
Using so-called second-generation technologies to convert material such as crop residues into bioenergy has a role to play and avoids competition for land. A challenge will be to do this at scale, since most of these residues are already used for animal feed or needed for soil fertility, and others are expensive to harvest.
How much of the world's liquid transport fuel would need to be from plants?
Biofuels and bioenergy take up finite land resources at the cost of food production and carbon storage and doesn’t guarantee carbon emissions cuts. Getting 10% of the world’s liquid transport fuel from plants – such as rapeseed, pictured here – would need nearly 30% of all the energy in a year’s worth of crops.
Why is land used for bioenergy?
Because land and the plants growing on it are already generating these benefits, diverting land – even degraded, under-utilised areas – to bioenergy means sacrificing much-needed food, timber, and carbon storage.
