Environmental sustainability involves conserving natural resources and protecting ecosystems now and in the future. It follows three conditions: renewable resources must renew faster than they are used, pollution must not exceed environmental capacities, and non-renewables must be replaced with renewables. Breakthrough Energy supports innovations to achieve net-zero emissions by 2050 through clean energy research. Renewable energy sources like solar and wind do not pollute or deplete over time. Tidal energy is produced from ocean tides but setting up tidal power plants is currently expensive with some environmental risks.

2. What is environmental sustainability?
Environmental sustainability is the responsibility to
conserve natural resources and protect global ecosystems
to support health and wellbeing, now and in the future.
Environmental sustainability is defined
through Herman Daly's 3 conditions:
The time it takes to renew
resources must be greater
than the time we take to
exploit them;
The release of polluting
particles into the environment
does not exceed its load
capacity;
The exhaustion of not-
renewable resources is
compensated by switching
to renewable resources.

3. Breakthrough Energy
Established in 2015 by Bill Gates and a coalition of private
investors concerned about the impacts of accelerating
climate change, Breakthrough Energy supports the
innovations that will lead the world to net-zero emissions.
At Breakthrough Energy, their mission is
to help lead the world to zero emissions by 2050
by supporting research and development.
“We bring people together to create
a world powered by clean energy”.

4. Renewable energy sources are forms of energy that do not
pollute and do not run out, since they have the ability to
regenerate.
Energy of the future
Renewables are destined to
become the most advantageous
source of electricity for the planet and for economic development.

5. New technology: Pavegen
Pavegen is an English company, which
provides for the creation of electrical
energy through the transformation of the
kinetic energy produced, walking, by man.
The flooring is lowered by a few millimeters and
then returns to its place. The energy, if necessary,
is stored in batteries.
How does it work?

6. Tidal energy is produced by the surge of ocean
waters during the rise and fall of tides. Tidal
energy is a renewable source of energy. There
are very few operating tidal power plants in the
world.
Tidal Energy
The problems of this energy
It is currently expensive to
construct tidal power plants as
they require high investments.
Environmental problems such
as habitat change, particularly
with tidal barrages.
