Transcript of Solar Power vs Wind Power for Individuals - Henrik Frank
Is it a better solution for “carbon neutral” homes to utilize on-site solar or
wind power or should these be provided in
commercial scale farms.By Henrik Frank
IntroductionWhy compare these two energy sources?
Many factors which are still debatableWhich of these two energy sources is more available?
Which is more landscape competent?
Which is more efficient?
Misinformation about both energy resourcesIt is claimed that wind turbines cause noise and disturb nearby residents (Wind
power)
Wind turbines accused of harming bats and bird populations of the locality (Wind power)
Higher number of birds are killed by other factors such as power lines, cars and high rise buildings. (www.conserve-energy-future.com/various-wind-energy-facts.php)
It’s a bad Investment (Solar power)
It destroys roofs (Solar power)
Cloudy days mean power outages (Solar power)
Issues of wind and solar power Wind Power disadvantages:
Expensive to buildHigh testing costsNeed large production sites
Unreliable energy (wind is not constant)Need transformer to transform the
inconstant energy into socket energyVisual and noise pollution
Placed at natural sites Up to 70 dB loud
Safety hazardFor birds and low altitude aircrafts
High manufacturing pollutionHigh maintenance costs
For checking the device
Solar Power disadvantages:Installing solar panels on a house is
expensive and requires experienced people
Often too expensive for the average homeowner
Giant solar farms built in desert regions Far away from area where power is
needed, therefore expensive transmission lines are needed
High maintenance costs and timesSolar panel must be kept clean and clear
of debris for them to operate at their most efficient.
The efficiency of solar cells currently ranges from around 20% up to a top range of around 40%
Article 1: Reasons to be cheerful: a full switch to low-carbon energy is in sight
Change between past and nowUnthinkable technology developmentRenewable energy seemed inaccessible
Due to the lack of technologyAnd the high costs
Solar Power costs around the world fell 15% in 2016
Problems of one individualThe end consumer does not often really think about how to minimize their footprintPeople were not very optimistic about renewable energy, because it was very expensive and inconvenient
Storage of energyThe storage technology of electrons is not yet properly developedWind and solar power are not consistent

Article 2: Solar power cheaper than fossil fuels in most
capital cities: Climate Council
Solar power costs Fall a further 40% - 70% by 2040 "In Australia, solar is now cheaper than new fossil fuels and nuclear power”
Advantages of Solar PowerHigher usage at lower costsSolar power developed to power in 600,000 householdsSolar power was more secure from extreme weather eventsSolar Panels 30% at home roofsClimate councillor Andrew Stock said:
Solar power is cheaperHas no fuel costsIs non-pollutingWill be a key of Australia's future
World DistributionChina, the US and Japan at the forefront of solar technology20 solar power plants in Australia slated to be built

Article 3: How Australia can become a renewable energy superpower
Renewable power growthEstimated Growth: $US 390 billion in 2013, to $US 2.3 trillion by 2035
To limit the global warming to 2°CDuring the energy transition phase it would be the best opportunity to change from non- to renewable energyA higher competitor to non-renewable energy industries
Non-renewable industries changeProblems such as global warming increased rapidlyThe temperature overshoot the 2C targetFossil fuel resources are “fast” disappearingHigh costs

Australia's Renewable Energy
AdvantagesAbundant
Low-cost renewable energy
Land availability
Proximity to the emerging Asian
Australia has one of the best renewable energy resources in the world
DisadvantagesOutdated and gold-plated electricity
network has acted as a ball and chain to progress.
Fossil fuel resources are fast disappearing
Article 3: How Australia can become a renewable energy superpower
Most potential in:● Australia● Generally in Africa
○ North-East Africa● Chile

Article 4: Energy alternatives: Electricity without Carbon
Capacity for wind power:The United States added 5.3 gigawatts of wind capacity in 2007
35% of the country's new generating capacity Has another 225 gigawatts in the planning stages
According to the Global Wind Energy Council, global capacity has risen by nearly 25% in the past five years
Wind Power Monthly estimates that the world's installed capacity for wind as of January 2008 was 94 gigawatts. If growth continued at 21%, that figure would triple over six years.

Article 4: Energy alternatives: Electricity without Carbon
Costs for wind power:Installation costs onshore around $1.8 million per megawattInstallation costs offshore between $2.4 million and $3 million per
megawatt$0.05–0.09 per kilowatt-hour (1981: $0.40 per kwh)
Competition to coal

Article 4: Energy alternatives: Electricity without Carbon
Capacity for solar power:Solar photovoltaic panel can convert 20-30% of the energy of
sunlight into useable electricity;Solar currently has the lowest capacity factor, at about 14%.Earth receives about 100,000 TW of solar power at its surfaceEnough energy every hour to supply humanity's energy needs for a
year. The world's entire primary energy needs could be served by less
than a tenth of the area of the Sahara.
Article 4: Energy alternatives: Electricity without Carbon
Costs for solar power:Manufacturing cost of solar cells is currently US$1.50–2.50 for a
watt's worth of generating capacityInstallation costs are extra
The price of a full system is normally about twice the price of the cells.
Photovoltaic solar power: $0.25–0.40 per kilowatt-hourConcentrated solar thermal power: about $0.17 per kwh
Article 4: Energy alternatives: Electricity without Carbon
Britain Energy Consumption vs Solar CoverageIn Britain one might expect an annual insolation of about 1,000 kilowatt-hours per metre on a south-facing panel tilted to take account of latitude: at 10% efficiency, that means more than 60 square metres per person would be needed to meet current UK electricity consumption.

Article 5: Wind Turbines versus Solar Panels (?)
ApplicationWind power is better in commercial scale power production than solar
powerLarge scale wind turbines are efficient and effectiveAt various location; far out to seaModern turbines are virtually silent Wind turbines are needed to be mounted high upAre often too loud for householdsGreat for small boats

Article 5: Wind Turbines versus Solar Panels
LocationWind turbines are very site specificSituated where more wind is blowingNeed to watch out against turbulent airWind power works best near coastNeed to watch out against turbulent air

Article 5: Wind Turbines versus Solar Panels
Stating the obviousA solar panel can generate electricity during the daytime when the
wind is not blowing.Some concentrated solar thermal systems get around this by storing up
heat during the day for use at night (molten salt is one possible storage medium)
A small wind turbine can generate electricity in a breeze when the sun's not shining

Unsuitable location:● Near to tree● Not high enough● To close to roof● Neighbouring properties
● Too loud; can be heard through roof
Main obstacles and issues
Finding hard data of individual homes
To answer the question and not to fade
Handling bias data of authors and not mixing them up
Having good facts supporting my argument
