## Introduction
For our project, we will be examining renewable energy information in Washington
State with comparisons from data sets of national averages. In our summary
section, we include raw data regarding the electricity supply in Washington
State and the energy consumption per state in the United States in 2018.
With these data sets, we examine how committed the Washington Government is
towards Renewable Energy, how Americans in general view it, and how
Washingtonians see it. Then, we look at three aggregate tables. The first table
explains the energy consumption in Washington state through 2000-2017. The
second table takes a deeper look into the energy consumption pattern in every US
state in the year 2018. The third and final table describes the situation of
energy consumption in the United States in 2018. We turn this information into
three data visualization including: Washington’s goal with the present energy
levels, Washington’s renewable energy consumption compared to other states in
the U.S., and the trend of renewable energy consumption percentage (2018) in
Washington compared to other states.
## Summary
```{r get_summary_info, echo = FALSE}
info <- get_summary_info(elec_supply_wa, energy_consum_state)
```
### How committed is the Washington Government towards Renewable Energy?
Since 2001, Washington State had the highest share of renewable electricity
supply out of total electricity supply in
`r info$ren_elec_supply_wa_max$max_share_year` at
`r info$ren_elec_supply_wa_max$Share` percent, while only an year before,
it had the lowest share of renewable electricity supply out of total electricity
supply in `r info$ren_elec_supply_wa_min$min_share_year` at
`r info$ren_elec_supply_wa_min$Share` percent. This shows how quickly the share
of renewable electricity supply out of total electricity supply in Washington
State can change within a span of an year. Hence, to properly evaluate the
Washington State's commitment towards renewable energy, the average share over
2001-2018 gives a better indication than the highest and lowest amounts. At
`r info$avg_elec_ren_supply_share_wa$avg_share` percent, we can say that the
state's commitment towards renewable energy has been moderate, since the amount
is right in between the highest and lowest percentages.
### How do Americans view Renewable Energy?
In the United States, `r info$highest_ren_consum_us$highest_ren_state` had the
highest renewable energy consumption in 2018 at
`r info$highest_ren_consum_us$btus` BTUs,
while `r info$lowest_ren_consum_us$lowest_ren_state` had the lowest at
`r info$lowest_ren_consum_us$btus` BTUs. However, that's an unfair comparison
because densely populated states are likely to have a higher renewable energy
consumption than that of less densely populated states. Hence,
renewable energy consumption per total energy consumption would give us a better
understanding as to how the people of each state view renewable energy. Now,
`r info$high_ren_cons_per_total$highest_state` is the highest at
`r info$high_ren_cons_per_total$percent` percent, while
`r info$low_ren_cons_per_total$lowest_state` is still the lowest at
`r info$low_ren_cons_per_total$percent` percent.
### Where do Washingtonians stand in terms on Renewable Energy, relative to The United States?
The average US Renewable and Fossil Fuel Energy Consumption in 2018 was
`r info$consum_us$avgbtu_renew_consum` and
`r info$consum_us$avgbtu_fossil_consum` BTUs per state respectively. The
renewable energy consumption in Washington was
`r info$wa_consum$wa_total_ren_consum` BTUs, with the renewable
energy consumption per total energy consumption standing at
`r info$wa_consum$wa_ren_consum_per_total` percent. Here we can clearly see that
renewable energy consumption in Washington is much higher than the national
average, and renewable energy consumption per total energy consumption is only
slightly lower than that of Oregon, which has the highest. Hence, we can see
that the Washington population is more than willing to move towards renewable
energy means and practices.

## Aggregated Data
#### Table 1: *Energy Consumption Percentages in WA 2000 - 2017*
```{r,echo=FALSE}
library("kableExtra")
kable(a, digits = 2, format = "html", row.names = FALSE) %>%
kable_styling(bootstrap_options = c("striped"),
full_width = F,
font_size = 12,
position = "left") %>%
scroll_box(height = "300px")
```
`*This table assumes that all forms of sun, wind, water, waste, and biomass
energy sources are renewable.
Over the course of 17 years, Washington's renewable energy sources
(excluding hydropower) generated <20% of the state's energy. The table reveals
that without hydropower, Washington can only sustain <5% of Washington's energy
requirement. This information is important as Gov. Jay Inslee pledged that
Washington would achieve 100% carbon-neutral power by 2030. Without hydropower,
Washington would have to look increase energy development efforts and look for
alternative sources of power.
#### Table 2: *Energy Consumption Percentages in individual US States 2018*
This table assumes that all forms of sun, wind, water, and biomass energy
sources are renewable.
```{r, echo=FALSE}
library("kableExtra")
kable(b, digits = 2, format = "html", row.names = FALSE) %>%
kable_styling(bootstrap_options = c("striped"),
full_width = F,
font_size = 12,
position = "left") %>%
scroll_box(height = "300px")
```
In 2018, the United States evaluated the amount of energy used by each state by
British thermal units (BTU). There is no dominant renewable energy source type
as energy produced by biomass and WWS are to some use in all states. The same
idea applies to petroleum usage and other nonrenewable energy sources. The table
reveals that nuclear energy is larger in bigger states. In the entire continent,
Mississippi (3.62%) had the least amount of its energy produced by renewable
sources and Oregon (44.44%) with the most renewable energy.
#### Table 3: *Energy Consumption Percentages in the USA 2018*
```{r,echo=FALSE}
library("kableExtra")
kable(c, digits = 2, format = "html", row.names = FALSE) %>%
kable_styling(bootstrap_options = c("striped"),
full_width = F,
font_size = 12,
position = "left") %>%
scroll_box(height = "300px")
```
This table tracks the energy consumption per billion BTUs. Over the last 30
years, it is observed that the US's renewable energy production fluctuates
around the 20-30% range (see percentage renewable energy (out of total)). The
renewable energy consumption grows relative to the increase in total energy
consumption. Nuclear energy consumption is comparable to biomass energy
consumption, whereas wind, water and sun energy (WWS) consumption is greater
than both. The US may shift their focus to expanding multiple energy sources
like nuclear energy and WWS to meet and hopefully completely fulfill the growing
demand for energy.
## Three Charts
### 1. Scatter plot of Washington's Energy Usage per Type from 2001 - 2017
```{r, echo=FALSE}
source("scripts/chart_1.R")
suppressWarnings(plot(chart_1(energy_per_src_wa)))
```
The scatter plot precisely tracks the trend of both nonrenewable and renewable
energy consumption in WA to see whether sufficients improvements have been made.
We are making this chart to verify whether Washington is on track to achieve
100% carbon-neutral power by 2030. The plot depicts an increase in renewable
energy sources, however, it flatlines from 2013-2017. Renewable energy points
are seen to have a steady increase in 2015-2017. The trend line hints that
renewable energy production is increasing, but only steadily.
### 2. Grouped Bar plot of Washington vs US Average's renewable energy consumption
```{r, echo=FALSE}
source("scripts/chart_2.R")
chart2 <- chart_2(energy_consumption_per_state)
chart2
```
This is a grouped bar plot of Washington energy consumption vs US average
(without Washington State) renewable energy consumption. The purpose of this
chart is to understand how Washington State is doing and to check whether we are
on course with our consumption of renewable energy when compared to the rest of
the states. It could be easily observed that Washington on average uses more
renewable energy.
### 3. Map of renewable energy consumption percentage
```{r, echo=FALSE}
source("scripts/chart_3.R")
chart3 <- draw_map(energy_per_state)
chart3
```
This map shows the percentage of renewable energy being consumed by each
state. The bigger the circle, the larger the percentage. Additionally, when you
click on a blue circle, you will get a pop-up box which shows the exact
percentage. The purpose of this map is to allow the reader to visually compare
different U.S states with each other. The map lets the reader comprehend the
information in a simplistic manner. Nonetheless, one key inference from this map
is that Washington has one of the highest percentage of renewable energy usage
in the United States.
