What Is Renewable Energy?

• Energy is generated by many different sources.
  Typically, your cars fuel is gas, and your
  homes electricity comes from coal plants. Those
  kinds of sources are called fossil fuels and
  they carry two main problems with them
• They are depletable. It takes millions of years
  to form, but we burn them quickly to
• produce energy. At some point, we will run out of
  all the natural reserves and we will need to get
  that energy from an alternative source.
• They emit greenhouse gasses. Whenever we burn
  fossil fuels to produce energy, they emit gasses
  such as carbon dioxide that contribute to the
  greenhouse effect. This
• phenomenon is where Earths atmosphere traps
  heat from the sun. This leads to an increase in
  Earths temperature which can harm all forms of
  life on the planet.
• The alternative to fossil fuel is called
  renewable energy. Renewable sources are natural
  sources that have opposite characteristics as
  fossil fuels i.e., they replenish at a higher
  rate than consumption and create far lower
  emissions than fossil fuels.

• Examples Of Renewable Energy
• Solar The most abundant one, even in cloudy
  weather! Countries with many hours of sunlight
  can bene?t further from solar energy, and it is a
  key source of any countrys energy mix. The
  Suns energy is 10,000 times greater than
  humankinds energy consumption, and technology
  allows it to be used in the most variety of ways
  heat, cooling, lighting, electricity, and
  fuel.
• Wind Weve made use of the kinetic energy
  generated by wind-moving turbines for a long
• time with windmills. Over the last few years,
  wind energy technology has really evolved to be
  a large part of electricity production in many
  countries.
• Geothermal Accessing heat from Earths interior
  and converting it to move turbines is
• called geothermal energy. Hydrothermal reservoirs
  have already been used for more than 100 years
  and are mature and reliable sources of energy.
• Hydropower It captures the energy of water
  moving from higher to lower elevations like
  rivers, for instance and it is the largest
  renewable energy source used to generate
• electricity. Nowadays, it also comes from
  reservoirs with stored water hydroelectric
• plants. Those plants can serve multiple purposes
  beyond energy like providing water for
  drinking, irrigation, ?ood/drought control, and
  navigation.
• Ocean energy Uses the kinetic and thermal energy
  of sea waves to produce electricity or heat.
  This source is still in the early stages of
  development, but the theoretical energy
• potential surpasses worldwide human energy
  demands.
• Bioenergy It is produced from biomass e.g.,
  wood, charcoal, dung, or others as heat
• or power sources. Also, it has agricultural
  purposes, and most of it goes to rural areas to
  be used for cooking, lighting, and heating.

• What Is Carbon Impact?
• Now that weve de?ned what the various sources of
  renewable energy are, we can see that each form
  of energy generation has an environmental impact.
  Fossil fuels, such as coal or gas, when burned
  to produce energy, release greenhouse gases
  (often termed GHG) into the atmosphere,
  contributing to the greenhouse effect, and
  therefore to Earths temperature increase and
  harming all forms of life.
• What Is The Impact Of Renewable Energy?
• Renewable energy has signi?cantly lower emissions
  than fossil fuels for generating the same amount
  of energy. The speci?c amount depends on many
  factors such as the type of renewable plant,
  its size, and its purpose (e.g. heat or
  electricity). Hydropower plants, for example, can
  be a relatively clean source of energy but large
  water reservoirs can negatively impact the
  environment, causing ?oods, extinction of fauna
  and ?ora. Despite this, renewable energy projects
  can be extremely bene?cial to communities and
  the planet
• Can replace fossil fuel in the grid. If renewable
  energy is available, it is a no-brainer to
  replace fossil fuel for it. NREL study says that
  if 35 of energy comes from renewables,
  emissions are 25-45 lower depending on the
  mix.
• Can be built with minimal environmental impact.
  All power plants have an environmental
• impact. As technology advances, projects such as
  wind plants and solar plants have the lowest
  environmental impact to be built and can also
  have a positive economic impact in their
  regions, such as an increase in jobs.
• Can satisfy energy demands around the clock.
  Renewables can be managed, stored in
• batteries, and meet humankinds demand for energy
  by itself. Battery storage has seen an 85 price
  drop in the decade and has increased e?ciency by
  90 with no added GHG
• emissions. Just to illustrate, countries with a
  lower number of sunny days in the world still
• have high solar generation penetration Denmark
  (139), Germany (89), and Ireland (88)
  achieved remarkable usage of photovoltaic panels.
• Can be set up faster and last for decades. Solar
  and wind farms take less than 2 years to be
  built, vs 4 years of a gas-?red power plant. The
  lifespan of renewable facilities is
• estimated to last 20-40 years, and technology is
  advancing to make it even better.

• Why Would You Care?
• There are bene?ts other than environmental to
  going clean
• Renewable has never been cheaper. BNEF says that
  the cost of solar energy worldwide is
• 50/MWh, compared to 300/MWh a decade ago.
• Renewable energy projects can also have
  co-bene?ts with their communities. Wind
• plants can generate farmers and ranchers
  4,000-8,000 revenue per turbine, by renting
  their properties to wind farms.
• Dyme invests our pro?ts in renewable energy
  projects in our communities and schools. As we
  looked at ways to reduce the amount of CO2 in
  the environment, we believe that renewable energy
  offers the most effective means per dollar
  invested. Even more so than buying carbon
  offsets. And most importantly, creates jobs and
  reduces energy costs for our communities, while
  having a bene?cial impact on climate!
