 Renewable energies (or renewables)
are ways to generate energy from
(theoretically) unlimited natural
resources. These resources are either
available with no time limit or
replenish more quickly than the rate
at which they are consumed.
 Renewable energies are generally spoken of as opposed to fossil fuel energies.
The fossil fuels’ stocks are limited and non-renewable in the human timescale. The
most known examples of these resources are coal, oil or natural gas. On the
contrary, renewable energies are produced from renewable sources. Here, we’re
talking about energy coming from solar rays, wind or water cycles – all
theoretically unlimited on a human scale time.
 Renewable energies are also often referred to as “green energies” or “clean
energies”. Still, this doesn’t mean that these energies aren’t harmful to the
environment and have zero impact. Nonetheless, they have a low environmental
impact compared to fossil fuels. That’s why they’re increasingly becoming
important elements in companies’ Corporate Social Responsibility strategies in
terms of sustainable development.
 There are several types of renewable energies that are produced by different
sources such as the sun, wind or water. In fact, these renewables’ power
consumption has been growing over the last year. They have provided 8% of the
world’s electricity in 2017 and they now cover 1/3 of the power mix in Europe. At
the same time, the energy grid gets 1/4 of the total energy in China and 1/6 in the
United States, India, and Japan.
 This type of renewable energy comes
directly from the capture of solar
radiation. Here, the solar radiation is
absorbed by specific sensors and
rebroadcasted following 2 possible
operation modes:
 Capturing sun rays and directly
converting them into energy through
photovoltaic solar panels;
 Capturing, collecting and turning the
sunlight into heat that warms up
water or air.
 Hydro-electric power consists in the
transformation of the kinetic energy
of the water (from rivers, dams,
marine currents or tides) into
mechanical energy by turbines.
 Biomass is made up of organic
materials from plants or animals that
contain stored energy. The combustion
of these natural materials produces
renewable energy. Some examples of
generating energy from biomass are:
 Directly burning solid biomass like
garbage or wood to produce heat;
 Converting biomass into biogases such
as methane or CO2 due to the bacterial
activity that happens in the absence of
oxygen (as is the case in landfills);
 Using sugar or corn crops to create
biofuels such as bioethanol or
biodiesel and mixing them with fossil
fuels afterward.
 The Earth generates and stores
geothermal energy. In other words,
radioactive materials decaying inside
the Earth are emitting energy.
Electricity can be created using
directly or indirectly this
energy, depending on the technology
implemented. There are 3 main ways to
use geothermal energy:
 Generating electricity directly from the
Earth’s heat;
 Producing heat directly from hot water
boiling on the planet’s surface;
 Using pumps over the shallow ground
to heat (and also to cool) buildings.
 A management system is the way in which an organization manages the
interrelated parts of its business in order to achieve its objectives.
 These objectives can relate to a number of different topics, including product or
service quality, operational efficiency, environmental performance, health and
safety in the workplace and many more.
 ISO (International Organization for Standardization)
is an independent, non-governmental, international
organization that develops standards to ensure the
quality, safety, and efficiency of products, services,
and systems.
 ISO certification certifies that a management system, manufacturing process,
service, or documentation procedure has all the requirements for standardization
and quality assurance.
 ISO 50001 was developed for organizations committed to addressing their impact,
conserving resources and improving the bottom line through efficient energy
 ISO 50001 is based on the management system model of continual improvement
also used for other well-known standards such as ISO 9001 or ISO 14001. This
makes it easier for organizations to integrate energy management into their overall
efforts to improve quality and environmental management.
 ISO 50001 provides a framework of requirements for organizations to:
 Develop a policy for more efficient use of energy
 Fix targets and objectives to meet the policy
 Use data to better understand and make decisions about energy use
 Measure the results
 Review how well the policy works, and
 Continually improve energy management
 Like other ISO management system standards, certification to ISO 50001 is possible
but not obligatory. Some organizations decide to implement the standard solely for
the benefits it provides. Others decide to get certified to it, to show external parties
they have implemented an energy management system. ISO does not perform
 A fitness organization is a body that provides research, education, training, and
certification to the fitness industry. Usually, the organization will charge a
membership fee to join. And, because there is a monetary cost involved with
joining a fitness organization, you should think carefully about the value you will
receive from investing in a membership.
 One of your key responsibilities is making sure your staff is up to date with the
latest trends in the industry. The content that fitness organizations produce is key to
 Once upon a time, fitness organizations were just regional or local bodies that were
irrelevant on national or global stages. Imagine getting certified by a local fitness
association and then changing your location — your certification wouldn’t carry
much weight in your new area. Standardization brings uniformity on a national or
international stage, and also brings the benefit of guidelines. This results in more
credibility to your niche and the fitness industry as a whole. Such guidelines are
also great for safety and accountability.
 Say you’d like to concentrate on a specific niche, like group exercise for older
adults, for example. Some professional organizations may offer training and
advancements through certification exams to increase your experience in a
specific niche and help you become specialized.
 Your employees will perform a lot better with the right credentials and certificates,
and your members will be more confident in them. Having a certified personal
trainer on your staff looks a lot better than having a self-proclaimed fitness fanatic.
Make sure the certification programs are accredited, and by a reputable
accreditation agency
 Fitness organizations provide excellent networking opportunities. They enable you
to interact with other fitness professionals in your area, your country, and around
the world through conferences, events, and even social media. Conferences are
also great ways to earn CECs (Continuing Education Credits).
 Fitness organizations are reliable information hubs for new trends. This includes
new trends in technology. Tech is driving a lot of change in the industry, especially
through things like fitness trackers and management software so you need to be
aware of what’s coming in the future.
