This video sheds light on where biomass used for bioenergy comes from. The industry makes use of residue and wood that cannot be used in other sectors as a source of energy.
As part of sustainable forest management, bioenergy provides energy, rural development, GHG emission reductions and increased forest resilience.

BECCS, or Bio-Energy with Carbon Capture and Storage, is a technology that the IPCC has factored into their climate modelling. If it is to have the effect of keeping their models to well below 2 degrees Celsius of warming compared to pre-industrial levels then it will need to be implemented on a vast scale around the globe.
This week we take a snapshot of scientific and journalistic analysis of this controversial proposal.

5 types of Renewable Energy including solar,wind,ocean,hydroelectric and geothermal energy.
Science Standard: S6E6 a. Ask questions to determine the differences between renewable/sustainable energy resources (examples: hydro, solar, wind, geothermal, tidal, biomass) and nonrenewable energyresources and how they are used in our everyday lives.

This free and open source turbine can be built for half the cost of a 120 watt solar panel, and will produce about ten times the power (5kWh with 3m drop and 35 l/s flow) per day. It can be plugged into any appropriate waterway without the need for earthworks, and uses only basic off the shelf and recycled materials, and simple hand tools.
Details on materials, tools, and step by step build instructions are available (free) at:

Energy efficiency is an important element of NVIDIA’s environmental strategy in both product development and in how we run our labs and data centers. In this installment of NVIDIA in a Minute we hear from employees who are getting it right by finding ways to squeeze every last drop of performance from their equipment and space, while doing so in an energy efficient manner and reducing waste.

Script:
Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate.
The wind is produced as a result of giant convection currents in the Earth’s atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there’s no electricity.
Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.
